Fluids - Multifluid Manometer Example #2

Another multifluid manometer example. This time the end is not open to the atmosphere. Instead it is connected to a pipe that transports gasoline. All our fluids are given to us in specific gravity, which we can easily convert to density or specific weight.

I finally figured out what I was doing wrong. I was using kPa in my calculations but now I know we must convert to Pa. Thank you!

[@asoaso5324]

An inverted differential manometer is connected to two pipe A And B carrying water under pressure as shown in fig.2.26. the fluid in the manometer is oil of specific gravity 0.75 .Determine the pressure dufference between A and B

In the future could you just zoom out instead of scrolling around

[@alexwalton2132]

why don't you make your own video instead of hustling???

[@ryancopetti3850]

@@alexwalton2132 why are you mad over someone else's suggestion?

[@only_comments]

@@alexwalton2132 he has a right point.. main purpose of making video is to make people understand.. He was just giving suggestion..

[@TheSunshineRequiem]

wow thank you for mentioning why we treat air and liquids differently, I was confused even though its obvious...such details are always helpful

[@chrisrica6830]

This video helped me relearn manometers for my FE Civil Review. Thanks!

[@zolbayr480]

So the pressure of the air is still 370000Pa? Can i say the gas pressure is 370000Pa?

[@stephenfulmer8646]

How would you find the absolute pressure for this problem??

[@kierenhetherington6772]

Hero. Saved me going mad trying to figure this out :-)

SIR , YOU CHANGED MY LIFE

[@Rose-yw8yf]

Who’s has fluid test? 🤦🏻‍♀️

[@lugh6184]

Was too late to see this.. Now I just got 60%

[@KarthikArmstrong]

Did u have this question for your test lol?

[@NK-iy6if]

Thank you so much the video is very helpful! God bless you!

[@elnabz4731]

please why did you multiply mercury and gasoline with 9.81 and didnt for others?

[@petepenner938]

Nabeel lee I multiplied all liquids by 9.81 so I could find pressure. Pressure is the density of the fluid(rho)*gravity(g)*difference in height(h). The only term not multiplied by 9.81 is air since it is already given to us in pressure.

Whyy is the sound sooo low :)

[@Youtuber-rf4oj]

Simply thank you very much 🙏🙏

[@edgarquis6458]

Well explained congratulations.....!

[@xrhst0s2114]

What if we are given air ρ=1.2kg/m^3 then we take height into account?

[@MrThorkell1]

Then you just used that given density. That doesn’t change the process shown in the video.

Thank you so so so so so so so so so much :)
