- เผยแพร่เมื่อ 13 ก.ย. 2017
- This chemistry video tutorial explains how to solve manometer pressure problems in addition to explaining how manometers work. It also provides an introduction into barometers which are used to measure atmospheric pressure. Manometers are used to measure the pressure of a gas by measure the height difference between the fluid based mercury columns and adding or subtracting that value from the atmospheric pressure.

On a serious note, this guy deserve the best. I ALWAYS watch his videos after Lecturer lessons & understand moo better. thanks for everything
Surely you are Professor
this guy has the most cutest voice ever...thanks amazing lesson may GOD PROTECT AND BLESS YOU
Ikr ? Just what i thought
You're a lifesaver!! My brain was malfunctioning for all these hard science things but you explain it soooo easily!! Love your trigonometry, calculus, chemistry, and every playlist and videos there is!!
DUDE.. I LOVE YOU MAN. TELL ME YOUR NAME I'M NAMING MY SON AFTER YOU.

My man! Love the clear and simple explanation of this complicated model. Have a nice day!
Had a question exactly like this and had no idea how to do it, after 5 minutes I know. Thanks for the great video :)
Professor Organic Chemistry Tutor, thank you for a beautiful explanation of How Manometers work on planet earth. The Manometer problems are simple to follow, however; understanding how pressure works inside of a tube is problematic. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
Ayyyyyeee my go-to youtube professor for all my STEM classes. You're the best!
I kid you not was scratching my head for an hour class calculation practice problem. Came on here sure enough figured it out in a few seconds. You’re an hero JG🥳. Thanks
Thank you very much for the excellent video. You explained this tricky topic in a rather simple and easy-to-understand manner.
My teacher took 1 hour to get this concept in our heads and was very unsuccessful by doing so,with ur 10 minute video,I understood everything.
great tut, explained exactly what I wanted.
Very nicely explained. Cleared all doubts . Thanks
Thank you!! you have saved many of my Chem tests XP
Thank you very much, i have been suffering with this for a long time and now ur explanation has brought relief to me.
thanks alot😇😜
My current textbook doesn't even fully cover how to get answers from a manometer, and other examples were too complicated. This was exactly what I needed to solve for, thanks for the explanation!
Such perfect explanation, you just got a new subscriber.
Your videos are very helpful. Thank you and please make more.
Thanks bud this was really helpful and straight forward cos I watched a lot of videos and they were not only long bud also useless
Thank you for this video, very educational and helpful.
this is really nice. it helped me quite a lot..
To be honest you are the best . 👌
It was a great presentation and I really appreciate you ❤ 🙏
You are a gift to the science nation....Thanks
you're so awesome and amazing at explaining things, just makes me want to cryyyyyyyy. Thank God for your lifeeeeee
Thanks man you simplified it
Language can't stop science
I understand everything ❤️❤️
This helps me understand more about my report, thank you man!!! You are very amazing!!!.....
👌👌👌
easy peasy lemon squeezy
Always find the common ground between the two sides.
Greatly explained sir.. love from India
Got it thanks im learning for igcse exam and like 15 topics coming but i leaned 90 percent of them
Outstanding sir!👌🏻
you are a true kd =. good job
Wow so helpful!😀
Great. Be blessed
Thanks sir!
Bruh you're a legend
excellent man you r awesome man
This helped me muchh. Thanxxx🤍🤍🤍
Too good❤❤❤❤❤❤
How do you have a FREE yt channel u deserve more
thank you so much
This guy is a god 😩
His voice reminds me of headspace ads
bro thank you so much
thank you
HE IS VERY GOOD
God bless you man
Thanks bro
Thx man 🙏
thanks homie
Will you be covering gamma values?
I didn't understand how can we add the value of pressure to the difference in height or the values 50 and 60 are in mmHg can you explain me?
Thanks

Good
OMGGOODENESSSS THANKSSSSSS
Thanks
can the formula used to calculate liquid pressure phg used to calculate air pressure given density of air ,height of air and g
Does the answer depends if the manometer is Closed or Open?.
How much bigger barometer required which gives Gwh electricity turbine turned by its moving of fluid due to atmospheric pressure
What if we make a manometer which turned the turbine of GWh electricity so we got extra energy from atmospheric pressure ?
You are good buh your questions are too easy
one of the limbs of a mercury manometer is connected to a gas cylinder the mercury level in the limb connected to the gas cylinder is 10 cm higher than that in the other then the gauge pressure of the gas is____cm of hg. I got 66 cm of hg but the answer says -10 cm of hg. Am I right or is the book right?
i love u with all my heart
Man i love youuu
helpfull
I'm probably wrong, but I don't think a partially filled tube with 720mmHg will raise to 760mm when flipped into the Hg tank. The tube has to be COMPLETELY full before flipping, otherwise you a have 760mmHg air pocket in your tube--the level will not change. If you had 780mmHg, yes it would drop, the outside atmospheric pressure is too weak to support more than a 760 mm column of dense Hg.
I am probably worng but don't think aproblity filled tube 720mmhg problem Hai
I feel what you said makes a good sense
Thanks

Does the patm have to be in mm or can it be cm???
if you use mercury it will be in mm but if you use another liquid (less denser) it might be in cm...for instance water...has 10.3m of height to equal the weight of 1 atm..this experiment was actually first carried out by accident in italy where the underground water couldnt reach a heinght higher than 10.3 m ...th-cam.com/video/EkDhlzA-lwI/w-d-xo.html check this out for more info..
I saw the thumbnail and I had to click jeez
i didnt understand , why did he add 760 to 60 ? like why should we add pressure + high ?
Exactly. That's also what is confusing me right now 😐
That's what I couldn't understand
Dope Boston accent 👌🏻
What ???
That may be a "gauge" Boston accent. The following URL documents an "absolute" Boston accent ... th-cam.com/video/r0IQCLQDfKw/w-d-xo.html
Using meters as your units for pressure is really throwing me off. Pa or atm? Since when is meters a unit of pressure?
meters are not a unit of pressure. "millimeters of mercury" is. its the same thing as torr. Youve heard of torr right?
you speak less and you do more
thanks a lot

A turbine of TWh electricity turned by a bigger barometer so we got energy round the world and free
Pls anybody tell me what is
mm hg
millimeters of mercury
