Example-Manometer Equation

[@MaxOnTrack]

I genuinely appreciate all you intelligent guys posting these kind of videos, they are brilliant

[@hassanliban6030]

Thank you. This method is how I first learned the subject, but I forget it over the years. Thank you for posting it.

[@rceby2024]

Dude, this video cleared all of my doubts, thank youuu!!! 😭

[@muhddanial1]

amazing. You made me understand the concept in mere 6 minutes! ty so much

[@erikkoh2462]

Excellent. You explain things better than my professors!!

[@serenaucsc]

Best 6 minutes spent on RUclips.

[@mayankpatil8492]

still helpful in 2019...very few problems on compound manometer to be found online...thank you

[@tyroneupton573]

This is amazing. I only wish my lecturer could be as clear as you.

[@DrDonElger]

Thank you for your kind comment!

[@sagardey342]

Oh god!finally i got the solution!THANK YOU

[@ArchimondetheDestroyerofWorlds]

this is the exact question for my tutorial. thanks :)

[@Sketches8]

wow thanks Don! You helped me greatly!

[@abumaalik9272]

Method is very clear, great

[@BhaarathRamesh]

Thank you very much,Sir. :') I wish I were a student of yours. :)

[@balabadrunineelima8133]

thank you very much sir. ur video is very useful

[@nihnagjagjit]

thank you soo much. you are a life saver!

[@xAlcoholicGamer]

very useful thank you for teaching.

[@ronelledatuin1778]

may i ask why did u add the h's of H2O?
i mean the formula says p1+(sum of pressure UP)-(sum of pressure DOWN)...
and makes the positive numbers in the PRESSURE DOWN negative..
so it shud be (-yH2O(0.6))?? am i right?

[@sampyhardin6689]

This is the best video yet, but... what about gravity?

[@HAfusion]

if its open to atmosphere shouldnt the atmospheric pressure be included?

[@DrDonElger]

HAfusion Gage pressure should be used on this problem. Thus, p_atm is not included.

[@TheSunshineRequiem]

P1 is the P_atm

[@leeshanpillay1253]

Hi Mr Donald Elger or anyone that did this problem taking P1 as atmospheric pressure at 101kpa and got a final answer as 190.47kpa for the pressure at A? Please reply if you got a similar answer.
Much Appreciated

[@mezajose6540]

Hi Leeshan, the Pressure at A is 190,47 KPa (absolute pressure), always remember Pabs = Pgage + Patm, it results adding to the the gage pressure obtained the value of the atmospheric one (101KPa). Regards.

[@jokev6580]

how did you choose where to locate 1 and 2?

[@DrDonElger]

Situate one of the points at a location where elevation and pressure are known. Situate the other point at a location where you want to calculate something such as pressure or elevation.

[@ericleonardo3911]

Sir,i have a question,why is the pressure at P1 is zero?

[@DrDonElger]

It is best to use gage pressure for a manometer. The gage pressure at 1 is zero. This is because gage pressure = local pressure - patm. Since the local pressure at 1 equals patm, the gage pressure at 1 is zero. Hope this helps.

[@DrDonElger]

Use gage pressure for a manometer. The gage pressure at point 1 is zero.

Thank you very much!

[@eraserman34]

You da real mvp!

umarım bu videodan sonra su tesisatçılarına patlayan su boruları için para vermem. dolar cm-hg kaç cm basınç gösterir sence ?

[@IamChandEvil]

Fantastic
