쉐도잉 연습: Water Flow and Water Pressure: A Live Demonstration - 영상으로 영어 말하기 배우기

레슨 만드는 중...
1
Hi folks, a lot of people out there, probably yourself included, if you're homeowners you deal with potentially what you call water pressure problems
2
and people don't understand that it's probably actually a water volume problem.
3
It's not a pressure problem and I'm going to demonstrate that for you in very simple terms.
4
I'm not a scientist.
5
I'm not going to get in any kind of technical jargon that you might not understand and I probably wouldn't understand.
6
So we have pressure gauges on two different lines here.
7
One's on an inch and a half line.
8
It's showing about 30-35 pounds of pressure and this is on a three-quarter line.
9
You know there might be a small kink in one of the lines.
10
It should be identical.
11
This is showing 40 pounds of pressure, but they're being fed by the same exact source.
12
So the pressure is the same, but the volume is vastly different.
13
So I'm going to give you a quick example, probably the only technical ease I'm going to get into.
14
If you have a one inch water service line in your home,
15
it's measured by how many gallons per minute it can provide, which is eight gallons per minute, which is barely enough for a one-family home,
16
according to New York City sizing tables.
17
An inch-and-a-quarter line, which is larger, inch and a quarter, one inch, maybe cost $150 difference if you completely change your water line,
18
gives you 75% more water, gives you 14 gallons per minute for about $150.
19
Now I'm going to get in, that might be the last technical thing I'm going to show you.
20
So, 40 pounds of pressure.
21
Okay.
22
Now, because it's interesting, because this hose is small,
23
it still has resistance to the water flowing through.
24
It still registers about 15 pounds of water.
25
There's an interesting point.
26
When you restrict the flow of water, increase the pressure and you know that
27
if you put your finger over the opening of your garden hose well that's more pressure
28
but it's less water and that's the same principle for
29
when you're taking a shower you have a shower head it
30
makes the water have more pressure same thing with your sink same thing like I said with the garden hose
31
so we're gonna shut this off now what you're going to see,
32
which should be interesting, this is an inch and a half line,
33
pretty much identical water pressure.
34
When I turn this on, you remember how this was spraying out?
35
This has no restriction on it.
36
That's all you're going to get out of it.
37
Because the flow of water is not being restricted, it's less pressure unless I restrict the flow.
38
Then I get more pressure.
39
You'll also notice that the gauge went down to zero.
40
Why did it go down to zero?
41
because there's no restriction on the flow of water.
42
The gauge drops to zero.
43
Three-quarter inch hose, it drops to about 15 because the garden hose is still restricting the flow.
44
So that's the beginnings of the difference between pressure and volume.
45
If you have a three-quarter inch line, you're not going to service your home, even though it looks like more pressure.
46
An inch and a half line, you could have a three-family home.
47
So what we're going to do is, you think same pressure, it should fill up a water bottle in the identical amount of time.
48
Except for the difference in gallons per minute that the inch and a half line will provide, the flow.
49
So this is the live part of the demonstration, a little bit of an unscientific demonstration, but I think it'll show that a lot of people,
50
a lot of folks out there, if pressure is the same, the amount of water is the same.
51
This is the definitive, a definitive test to just easily show you, not true.
52
We'll give the 3 quarter inch line a bit of a head start
53
and we'll see what it takes to fill the water bottle.
54
Inch and a quarter line, I'm going to get a little wet.
55
I'm going to get real wet.
56
Look at the difference.
57
Look at the difference.
58
Over double, over double.
59
Same water pressure, over double the amount of water.
60
Okay so from these simple demonstrations you should clearly understand that the gallons per minute,
61
the flow rate, that's what increases and improves your quality of life.
62
You have enough water, enough water for all your fixtures.
63
Pressure is a separate and distinct issue.
64
It's not usually the problem you're going to deal with.
65
this should really clearly be an example as to why that's true.
66
Thank you for listening and I hope that helped you out there.

이 비디오로 말하기 연습을 해야 하는 이유는?

이 비디오는 물의 흐름과 압력에 대한 실시간 시연을 통해 중요한 개념을 쉽게 설명합니다. 이러한 설명은 영어 학습자에게 과학적 주제를 이해하는 데 도움이 됩니다. 설명자의 간단한 언어 사용은 여러분이 새로운 어휘를 배우고, 복잡한 문장을 이해하는 데 큰 기여를 합니다. 또한, 다양한 어조와 강세를 통해 실제 대화 상황을 접할 수 있어, 영어 발음 교정과 유튜브 영어 공부에 매우 유익합니다.

문맥 속 문법 및 표현

  • It gives you 14 gallons per minute. - 'gives'라는 동사를 통해 '제공하다'는 의미를 쉽게 이해할 수 있습니다.
  • You remember how this was spraying out? - 과거형 질문을 통해 이 비디오에서 시연한 내용을 상기시킵니다.
  • If you completely change your water line... - 조건절을 사용하여 가정적인 상황을 표현합니다.
  • When you restrict the flow of water... - 시간 부사절을 통해 원인과 결과를 연결하는 문장을 배울 수 있습니다.

일반적인 발음 함정

이 비디오에서 주의할 만한 발음 함정은 ‘pressure’와 ‘volume’입니다. 특히, ‘pressure’는 발음 시 강세가 중요한 단어로 정확한 발음을 연습하면 도움이 됩니다. 또한, shadowspeaks와 shadow speak와 같은 단어를 연습함으로써 영어를 더 유창하게 구사할 수 있습니다. 이러한 단어들은 실생활에서도 자주 사용되므로, 반복적으로 연습하여 여러분의 발음과 억양을 개선하는 것이 좋습니다.

이 비디오를 통해 단순히 내용만 이해하는 것이 아니라, 자연스럽게 영어로 소통할 수 있는 능력을 키울 수 있습니다. 따라서, 여러분의 영어 실력 향상에 큰 도움이 될 것입니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
