Hello, this is Enna.

Today I'll talk about unexpected situation during last event filming.

Work was not hard.

I setup camcoder as usual.

But,

Condition of field was different.

Not normal.

You may know after seeing sample.

I'll talk about problem after that.

As you see, sound condition is not good.

Orator and crowd's sound is mixed.

Because, fields structure was unusual.

Normally speaker's position is front of audience.

But speakers were fixed to street light here and there.

Sounds did not come straight. Sideways.

It's hard to gather sounds like that with shotgun mic.

I found sound condition is bad during monitoring.

'I can't record sounds clearly with this way.'

I had to find solution.

But had only 3 minutes before start.

And didn't have recorder.

I noticed I packed emergency camera NX1.

So I choose using it.

I looked around and found fine place to set my camera (by the street light with speaker).

I ran to there and set my camera and record for clean sound.

Near the speaker and far from crowd.

After that I merged camcoder's screen and NX1's sound when editing.

I'll show you results before and after merging.

You may find merged sound is much better.

Clear sound and less crowd noise.

Theory and actual fight is different.

'Set this way and that way will work perfectly' but it's not.

My career is not long enough like 10, 20 years.

So sometimes I made mistakes also.

But it's important not to be panic and concentrate to solve problems.

So.. I talked about unexpected situation and solution today.

Thank you.

Simple Tuned length calculation 2 stroke chamber baffle cone, temp, gas effect on sonic velocity E4 - Duration: 6:18.

hello again 2 stroke fans. Yeah look up to the top of the corner you'll see

links to the previous video that this one's continued from so I won't recover

that I'll just get straight into the next one which follows on with the tuned

lengths, we have a tuned length between diffuser and exhaust port and our baffle

cone and our exhaust port, tuned length one and tuned lengths 2. I told you I'd give

you a calculation, this is the calculation, what it does in simple terms

is it takes the amount of time that the engine does in one revolution at a

certain RPM. So 10,000 rpm, so we figure out how long it's got to take and that's six

milliseconds that one, and then we divided by how many degrees in 360 is

the exhaust port open for so I'll say 180 so we divided by that, and then we know the

amount of time exhaust ports open for so say 3 milliseconds and there's RPM at

180 timing, and then we take our velocity which is the speed of sound

multiplied by the amount of time that we've got to see how much distance the

sound will travel, then we get a tuned length in both directions so it's up and back

from the baffle cone up and back, from the from a port to the diffuser cone and back.

So divide that by 2 because the tuned length 1 is only in one direction because we're

dimensioning that pipe. This figure here just basically makes our meters per

second into millimeters per second, if you used feet per second in this

equation you would just make that times 12 to give you tuned length in inches. Now

the velocity we're using, the speed of sound, I'm using a basic straight line

figure just for example purposes which is the speed of sound at atmospheric

pressure at 0 degrees and then the largest effect on the speed of sound

will be temperature changes so that's that figure times Celsius in

temperature. A smaller effect to some degree will be on the pressure and a

smaller effect on the on the sonic sound will be the gas composition of the

exhaust because it's not dry, in fact we've got hydrocarbon, carbon monoxide,

carbon dioxide, nitrogen oxides, so this figure will be variable based on not

just temperature, to a little degree the pressure and to a little degree whether

the mixtures are rich or lean or very rich, and as you can see if the mixtures

are not right after you've gone to all the trouble of of modeling the pipe and

the lengths, then it's not going to follow so that's where if you are going

to gather all the trouble of modeling this with more complex math than this going

down to the actual chemical compositions you got to make sure that your mixtures

actually follow that otherwise your velocity will be wrong and then you tune

length will be out. So we'll run this program and I will show you some basic

comparisons so I've got our figures here ten thousand rpm, one hundred and eighty

degrees timing, 350 degrees Celsius, 350 C a

straight line velocity uses 543 meters per second so tuned lengths is 815, so what

happens when we decrease the RPM okay.

nine thousand, increase it, our pipe length gets shorter and longer okay, shorter as

we increase the RPM, longer as we decrease the RPM, because time, the

amount of time we've got is decreasing as the engine, keeping in mind that the

sonic figure is constant, the amount of RPM increase we have means we've got

less time and if we have a lower exhaust timing likewise we have less time so if

we close the exhaust timing down exhaust timing open see, it gets shorter as we

close it down, like this, as we rev the engine up higher it gets shorter and

shorter because we less time that the piston is open for at

the given degrees we've got, Now if the temperature changes okay

go from 300, We're at 770 now we go from 300 to 400 rotate, we're at 813 that's the distance it

will travel because 400 degrees the speed of sound is faster, so as you can see the

temperature change will change to a difference, so let's say we've got 350

degrees which is their average temperature of the entire expansion

chamber because we're looking at the baffle cone part here, and our timing is 180

degree so 815 millimeters all right, so if we drop that, now it's shorter so now

we're going to go back up to 815 millimeters, so we go back up to about 819

millimeters the same figure then look at our rpm, 9400 so now a pipe that we

modeled to have a sweet spot of 10000 at 350 degrees now we've got temperatures

of 300 degrees sweet spot of the pipe's now

9400. So you see everything has a relationship with each other as far as

time it takes and the sonic velocity. Okay so that'll do it for now we're at our

time limit, and the next one will be the diffuser, the second tuning which I'll

explain exactly that the difference with the exhaust degree timing there, that

gives you a quick demonstration and I'll get the next video done for you tomorrow

Catch you then.

Present Simple - Duration: 17:10.

Okay..Now we're going to speak about the present simple tense..And as we said,

when we first talk about a tense, we should talk about when should we use it,

what should we use it for.As for the present simple tense, we should use it

when you speak about three things. number 1 : opinions,

number 2: habits or routines and number 3: facts. So whenever you talk about

or whenever you want to express your opinion or you would like to talk about

your habits or routine or you're going to speak about facts you should use the

present simple tense not any other tense. Okay ..Here are some examples about

the opinions. So when you talk about opinions for example you can say: I like

tea. Rehab doesn't like watching movies. okay. So these are some examples of

opinions. Some examples for sentences about routine and habits. You can say I

go to work every day.

She meets her friends every weekend.

We usually watch football on TV .So these are examples about routine and habits

Finally some examples about facts.

It's cold in winter. We need water to live. So these are

examples of facts. Okay ..So as you can see all these sentences are in the present

simple tense. Now what? Okay how should we put the verb in the present simple

tense? Should we add anything to the verb for

example? Will the verb be the same ?Okay.. so before we start this we should know

that we have two groups or two teams to make it easy for you. And here we are

talking about the "subject of the sentence" we are talking about the

subject of the sentence. As you know any sentence should start with a subject. The

subject can be... (Ahmed,Mona,Jack,James,..) or (I, you, he sh, it) okay here we are.. And

the first team if the subject of the sentence is one of these things( I/you/ we

they/ or plural noun )you just don't add anything to the verb.Just put the

verb as it is. Don't add anything .Don't change it at all .Okay..For example:

I like coffee. We study English. Ahmed and Muhammad play

football .So as you can see the verbs here are (like/study/and play) and

nothing has been added to the verbs.So we didn't say "likes" you didn't say "liked"

you didn't say "liking" you didn't say" will like". You just put" like" as it is. Okay. So

these are some examples of the present simple tense if the subject is one of

the first team, okay... Like we said: if the subject is( I/ you/ we

they/or plural). Okay. How can we put these sentences into negative?

We are still talking about this group. okay the same group so if the subject is

one of these (I/you/ we /they or plural noun), just add "don't" if you would like to

change the sentence into negative .For example: I don't like coffee. We don't study

English. Ahmed and Mohammed don't play football. So as you can see we said "don't

like", "don't study", "don't play". Easy, right? what about questions? How can you ask a

question in the present simple tense? First of all you should know that we have two

kind of questions. Yes or no questions and Wh- questions. Okay so now we

are talking about yes or no questions

For example: Do you like swimming? and the answer is: "Yes, I do" or "No,I don't."

Do you like Egyptian food? Yes, I do. No, I don't. So you should start your

question with do and the answer is do or don't. It's easy, okay? You can try some

examples yourself. You can say do you like football? Yes, I do.

No, I don't. okay Wh- questions and we mean

Wh- questions are those questions that start with (where, why how,

who ,when) okay not just do or does

so for example : Where do you live?

I live in Egypt.

When do you get up? I get up at 7 o'clock.

what do they eat for lunch?

They usually eat burgers.

easy ,okay. So now it's time for you to try your own examples. okay that was it

for the first team. what about the second team?

If the subject of the sentence is( he/she/it/ or a singular noun) like Jack James we

should add -s at the end of the verb, to make it in the present simple tense.

For example:

He lives in UAE.

She speaks English.

He plays tennis. Sometimes,

don't just add -s .when should we do this? If the verb ends with one of these

letters( s/z/ch/sh/o/x)we don't add just add -s. We add -es. for example. John

passes the exam .The phone buzzes suddenly.

He watches TV. She washes the dishes. Ahmed goes to

school.

The mechanic fixes the broken car.So,with these examples, we didn't just add -s we

we added -es because the verbs ends with these letters (s/ z/ch/sh /o/x). Now it's your

turn. Try to think of some verbs that end with

these letters and add -es to them. Sometimes ,we should add -ies if the

verb ends with (a consonant letter + y) We should change the "y" into "-ies". For

example: He studies English.

Ahmed carries a heavy bag. As you can see the verbs are "studies" and

"carries". The verb "study" "s-t-u-d-y" before the "Y "we have "D ", so we change the

"Y "into "-ies". The verb "carry" " c-a-r-r-y". It ends with "Y "and before the "Y "there is

"r" ,so change the "y" into "-ies". So that's it for the second team.So, remember if

the subject is (he/ she/ it/or a singular noun)

you can add -s/ -es/ or -ies.

Now, let's talk about negative. How can we change these sentences

into negative. Remember with the first team

we used" don't" but now we use "doesn't"

For example:

She doesn't watch TV.

She doesn't wash the dishes. Ahmed doesn't go to school. As you can see ,after

"doesn't", we just put the verb in the infinitive .By the infinitive we mean :the

verb as it is without anything at the end .We didn't say "she doesn't watches"

right? Wee said "She doesn't watch" so after "doesn't", remember to remove -s

-es or -ies . Just put the verb as it is. Okay...Yes or No questions.

For example: Does he live in Berlin? Yes, he does. No, he doesn't.

wo we started the question with "does" and answer with "does" or "doesn't". it's really

easy. Try it yourself. wh- questions

What does Aml like?

She likes reading books.

Where does she work ?She worls in a bank. So after the Wh- word,

we use "does". And remember all the verbs after "does "are also in the infinitive. so

"what does Aml like? "We didn't say "likes" Remember..! "Where does she work?"

we didn't say "where does she works" we said "work". okay Now we're going to speak

verb to be. Sometimes the verb of a sentence is not

action verb .It's not like ( play or sleep or swim or study or read )sometimes it's

verb to be. V.to.be in the present simple tense is one of these verbs(am/is/are)

so we can say "I am a teacher." you can say "I'm a teacher."

"He is a doctor". "He's a doctor". "She is my sister." "She's my sister."

In negative, just add "not". There is no need to say "don't" or :doesn't". If you have

verb to be in the sentence don't use don't or doesn't. So just to use "not"

after verb to be.

So, "I'm a teacher." "I'm not a journalist." "He's a doctor."

"He isn't a football player."

"She's my sister." "She isn't my wife."

With Yes or No questions, use(am/is/are) at the beginning of the sentence.

don't use (do or does) because you already have verb to be in the sentence.

For example:

"Are you okay?" "Yes, I am". "No,I'm not". "Is he happy?"

"Yes, he is." "No, he isn't." "Are they outside?" "Yes they are" "No they

aren't."

Wh- questions:

"How old are you?"

"I'm 25 years old."

"Where is Sarah?" "She is in the kitchen." so as you can see, we didn't use do or

does in the sentence. We just used (am/is/are) Easy, right? Now what? now we talk

about some of the key words that we can use to express the present simple tense.

We call them: "adverbs of frequency" because we use them

to talk about our habits. How often do we do something ...do we do it every day do we

always do it or do we never do it. Okay as you can see in the picture ,we have

some words and we grade them from 0% to 100% so if you do something all the time

you can use "always", then " , "usually" "often" or "often" , "frequently"," sometimes", "occasionally"

"seldom", " rarely", " never". Never means you don't do it at all .You never do it.

Some other key words that you can use .you can use "once". For example ..."once a week" "once a

month", "once a year". "From time to time" or "every now and then". Okay.. How can we use

adverbs of frequency? Where should we put them in the sentence? we have two places.

First with verb to be .For example: "He is always late." "I am always on time.

" You are never satisfied." As you can see he is always ,I am always ,you're never. we use

adverbs of frequency after verb to be so is usually, is sometimes ,is often, is

never .You didn't say usually is or sometimes is. Okay?

With other verbs. if the verb the sentence is not verb to be . It's easy!

For example :"We sometimes drink tea in the afternoon."

"My brother seldom smokes." So as you can see we put the adverb of frequency

before the verb not after it .So we said "we sometimes drink." We didn't "say we

drink sometimes" no.. no..."My brother seldom smokes". We didn't say "smokes seldom" . Good!

ok What about long time expressions? We can

use them in two places: at the end of the sentence or at the beginning of the

sentence. For example :"I meet my friend every now and then." So we write "every now

and then" at the end of the sentence.

"Once a week, I go to the shopping mall "."so once

a week" is at the beginning of the sentence. That's it !! now you know

everything about the present simple tense.
