Measuring Pressure With Barometers and Manometers 

0:58 Barometer 2:33 Hydrostatic Pressure 4:02 Manometer, measuring pressure exerted by trapped gas 5:00 Finding gaseous pressure 7:36 Comprehension Check

Came here for a simple explanation of a barometer 2 weeks ago, left with more knowledge and this weeks study material on manometers and atmospheric pressure testing for boiler draft. came back to say thank you for the thorough explanation, and great animated imaging for each. 10/10.

Well spoken, nicely explained and much better than the recording in my class. Nice job and thank you.

Amazing content, I love you for letting me understand this concept in such an easy manner, Subscribed

Wow, I wasn't expecting the hair cut!! But great video thx! It really helps me explain things to my students. I often make them watch your videos for homework :)

so far, i really enjoy your explanation. hopefully, i wish you make more content in your videos. thanks

Simple and clear explanation. Great video. Thanks!

THANK YOU SO MUCH I UNDERSTOOD EVERY DETAIL🖤

perfect explanation, thank you!

Best explanation ever, thank you 😊

EXCELLENT!! THIS HELPS ME A LOT!

Working to understand measuring pressure in a mechanical refrigeration system. Thanks for the help Dave.

Why are you so talented and brilliant?😭

Understanding easily, thanku so much 💖

Excellent work. Thank you for the educational material.

Very nice explanation of 'em!

Bruh a 7 minute video for free taught me more than the 1 hour lessons in school that cost us 1k a year

Amazing explanation thaaaaannnks!

Perfect sir I really appreciate your way of teaching......

Dude love your explanation.Thanx alot..........

Thank you, this was really helpful.

this absolutely saved me, thanks so much

Spectacular explanation 🙌🏽🙌🏽

Hi. Do you know a standalone instrument that can measure the pressure inside a hyperbaric chamber in ATA or psi. Is there a wrist worn unit that can do this. Thanks for your help.

Very nice explanation! Cheers from south Brazil 🤘🏻

YOU'RE THE GOAT OF EXPLAINING

This really helped thanks

Amazing! Thank you so much.

Great video!

Thanks very much It helped me .

I understood the topic I couldn't understand for 6 months thanks dave

Good one!

It was wonderful thanks

Thanks HELPFUL

Nice explanation

thanks professor Dave :)

Thank you sooooo much

thank you professor dave

thanks so much!!

Thank youuu❤

I LOVE THIS

thanks prof

Can i know the name of app u use it to draw manometer

Hi. I found this channel because of the flat earth stuff, but I can't stop watching your videos. It's so annoying to not understand it all, but at the same time a good feeling. Thanks man ♠️

as we go to a depth in a liquid the pressure increases but why is it opposite in a barometer?

Quick question, what happens to the levels on the right side and left side of a Utube manometer when the gas pressure reduces by for example 20 of mercury

Hey professor dave! I have loved your videos for a really long time, they helped me ace chemistry and physics. Question for you. I work in a brewery and my co worker and I were discussing pressure of a closed system. Our fermentors have a sealable door and a pressure gauge that reads between 0-30psi. We were discussing why, if at sea level 1 atm/14psi of pressure is acting on us due to atmosphere, why when do you seal a tank does it not have 14 psi worth of captured pressure and read at 14 psi. My coworker thought it was additive and that it is 1 atm + what ever additional pressure you add to the tank. So effectively the gauge is tarred at 1 atm. My thoughts are that the diaphragm pressure gauges are not designed to translate barometric pressure into something readable on the tank and thus only when you have a fluid or added gas to the tank do you see the translation to a reading on the gauge. From this video i would think that then if we were to use a manometer that we would see that 1 atm of pressure acting on the fluid in the manometer?

Please if the pressure exerted by the gas on the mercury is greater than the atmospheric pressure, does the atmospheric pressure still have an effect on the mercury to cause it to move even just a little bit?

Did you make a mistake in saying that the density is 13.6grams.. because the unit conversions is off. (going from grams to kilograms gives you a smaller number.)

So helpful

I saw the notification for this video immediately I opened it

You explained perfectly except when you got to the part about pressure of a gas but the atmospheric pressure exerts more pressure and the subtraction which confuses me

Me :sees the notification Me : clicks immediately Reaction time : am I a joke to u

great vid

6:55 why do we add?

Omgg this can't be true,I was just studying physics specifically manometers,barometers and so and I was very confused then I checked my phone to see the notification,wow

thank you sir

Isn't the Hydrostatic pressure also called Manometric pressure?

Hi Dave! Long time.. No questions, just here to say 'hi!

But in the closed-end manometer, what gas is above the liquid on the right side? Doesn't the pressure exerted by the gas in the vessel then also depend on the gas exerted by the gas on the right?

Thank u prof. You look good btw

professor Dave I have just noticed that if you search up how estrogen stops growth you get no results actually explaining how estrogen speeds up your bone age. I would highly appreciate if you were to rectify this issue on RU-vid as I think it would make an interesting video and no one else appease to have made a video explaining this.

I wish you had done an anaroid barometer as well 🧐

2:10 density of water 0.997? At which temperature and pressure?

Please upload vedio about particle physics gauge theory plz asap

What is efficiency of barometer Aniroid barometer

ILOVEU

Thanks, got my igcse physics test next Wednesday

哈哈哈，不好好学化学就得半夜自学了TT

2:33

Which accent is speaker speaking? Can anyone please reply

you look so good with your short hair haha

In maths, why do you not show how do we get the answer?

Mahna Mahna!

Thank you for sharing this great explanation I know a few flattards that need to learn about this stuff lol

Let's check the blood pressure

Hi layan😂💜💜

Put a turbine which is used in sea in this big model so we got a fresh distilled water turbine and very cheap source of energy for free

Make a barometer holding one crore litres of💧💧💧 water💧💦 so it's become a great👍 source of🔌 energy⚡⚡⚡⚡ forever😁😁😁😁

If we used one crore manometer and a common output for all of them so it's become a great source for energy⚡ or not 🤣🤣🤣🤣

Yea but you can't have pressure without a container, it breaks the 2nd law of thermodynamics. Prove we can have pressure. -Nathan Oakley's message INCOMING

One crore litres volume barometer produced how much pressure for making electric🔌⚡ power💪⚡ forever😁😁😁
