Open Tube Manometer, Basic Introduction, Pressure, Height & Density of Fluids - Physics Problems

This physics video tutorial provides a basic introduction into the open tube manometer also known as the u-tube manometer. It explains how to calculate the absolute pressure of the gas in the bulb and the gauge pressure given the height difference in the two columns. In addition, it discusses how to calculate the density of the unknown fluid. It contains plenty of examples and practice problems.

Open up utube app

[@emmanulluakila4302]

bro i a always impressed how this guy can explain a whole chapter in a few minutes . wish my lecturers was that simple

[@SamEmma-jk2hw]

This few minutes is million times better than 2hrs I spent to learn this in class. Thanks bro

[@redapples4422]

You are the MVP. It's my first week in thermodynamics and I was about to drop out because I didn't understand a lick of it and now im just cruising by the homework problems. Thank you for this valuable free content!

[@AhmedMohamed-pg2bb]

Bro you don't understand how much this helped me. Thank you ever so much!

[@whizzkidkis]

Thanks so much for the video. Helped unlocked something that wasn't clicking. Much appreciated!

[@ranawaleed4682]

Very helpful. This video clarify my all misconceptions. Thank you very much Sir.

[@cheese-bg1xq]

I struggle A LOT with physics, I just can't seem to understand or remember physics concepts at all (even GCSE-level) but it's somewhat part of my course. Thank you so much for these videos! They really help!

[@veenakirale1848]

i just have no words ,,,,,,,,,.......its best ..excellent i understood everything

[@najibabdishakur1118]

thanks dear teacher i always watch your videos whether it's physics or math thanks again keep doing

[@jenniferku5837]

thank you SO much for this video!!

[@tsionayalew1223]

The most advanced tutor in the world.

[@firstlegend5105]

This is very helpful for my Thermodynamics module for Engineering. 🙏

[@sababatamanna2117]

Thank you!💜

[@s.prabhavnarayan3416]

my physics exam is tomorrow, I full understood about open tube manometer calculations
thankyou bro.

[@amongojersond.8365]

thank you priiiii. this thing really helpss

[@satoseitoku]

This video is thousand times better than my professor's explainstion

[@zaralearningkorean]

No one:
Me before he even says it: in this video..

[@artingoodarzi4423]

you are a lifesaver

[@westy7846]

banger video my guy

[@pranjalverma3501]

Thank you sir.

[@nsaharshini9467]

Thank you soo much

[@_hasty]

thank you sm sir,you saved my grades(I have physics exam tomorrow)

[@giagarfin]

THANK YOUUUUUUUUU

[@chrisfourie7783]

Thanks mate this video saved me 40 bucks!!!!!

[@edpagan5421]

How? I wanna learn

[@edpagan5421]

How? I wana learn

[@nathan8472]

@@edpagan5421 he usually gives Joseph in our class 40bucks to cheat from him. now that he learned from the video he doesn't have to pay the 40 bucks

[@ZULFERISYAHPUTRA]

Dear Sir............Example Problem : One hydraulic cylinder, the end is connected to the Threaded rod so that it can be rotated. Cylinders with a bore size of 18 mm, 10 mm rod and a stroke of 300 mm single acting in a condition that is filled with oil. If the cylinder is rotated 10 mm.
a. How to calculate it
b. What is the gauge pressure

[@mileslegend]

Am going for a test... If it comes and I have smashed it... I will give you a five star rating

[@ayaaljmi6469]

Thanksss alot💕

[@realkingrey2732]

this is dope

[@d_lfas8106]

Thanks

[@johnmanuelm.escueta6987]

SALAMAT!

[@anjalibansal4063]

Thankyou

[@ronisuyono9978]

in the first number , what if the liquid is changed with water ? what is the solution and what parameters should be changed ? thx

[@ritesha8050]

Thx

[@lindaowusu1526]

Can you please vividly explain Pl=Pr

[@abcd6924]

A doubt: can't I take pressure in atm itself?? That's a pretty simple number---1

[@anilsharma-ev2my]

Why we cannot use a dam like a barometer which gives electricity without flow of water outside so we can provide electricity even if there no enough water in dam

[@luyandabanda2533]

For the u-tube manometer you didn't convert cm to m why??

[@markjoseph261]

Limitations of Peizometer : Gas pressure can not be measured because gas can not form a free surface

[@AkliluDemissie]

how can i know one of them are more pressure?without graphs

[@db2885]

Khan Academy my ass ! This is the best channel!

[@alexlow9714]

i dont understand the gauge pressure part. 6:21

[@universaljudge3790]

So if the gas pressure is less than the atm then it acts like a vacuum

[@deependraverma4382]

No, It doesn't act like that. Forces just become unbalanced. If it was a pure vacuum then the whole liquid is shifted to the other side because atmospheric pressure is 10^5 Pa and Vacuum pressure is 0. Hope it helps!!

[@amansaiyad7177]

you are beast bro!!!

[@jesscasandy5014]

i have understood even compared to when am in class🙄🙄

[@brilliant1863]

Damn Mark Wahlberg explaining fluid mechanics!

[@vg-qq6sw]

what about the 60 cm height

[@drewdavidson5501]

where does 9.8 come from?

[@xmertrix]

Gravitational acceleration 9.8 m/s^2 ρ(g)h

[@thibautverrue]

Hero!

[@weeyek3320]

When we neglect the atmospheres pressure?

[@marekjanik9962]

Whenever we can!

[@moecodes_]

when it's a closed tube. as long as air can access the tube you have to consider the atmospheric pressure

[@ZxNaba]

Menelantarkan

[@barreltapper]

So if the pressure of the gas is removed, the mercury would mount on the right side to the same level as the left side,, does this mean that gravity is pushing and pulling at the same time? In other words why does gravity need to find a level?

[@zyrojaymontero7631]

because gravity is a downward force acted upon things so we need to consider it.

[@kingjay688]

What if I’m not given the height of mercury?

[@nathan8472]

solve for "h" in the equation if other values are given.

[@JRockTT]

So if you just use the height difference of 600mmHg and convert to Pa, you calculate a slightly different value: 181,317 Pa. Can you reconcile? Especially given your video here: ruclips.net/video/8P5NlpxGT7Y/видео.html
Same for the second example: 47,995.92 Pa

[@abdulsaburharuna8234]

Pls is the:
A. The density of the gas is less than the density of air. B. The density of the gas is greater than the density of air. C. The pressure of the gas is less than atmospheric pressure. D. The pressure of the gas is greater than atmospheric pressure.
Thanks need answ. nowww

[@ranawaleed4682]

what have to find

[@Kurosaka]

*G O A T*

[@Kai26448]

I don’t understand 😭 i might fail physics help anyone pls
