This physics video tutorial provides a basic introduction into absolute pressure and gauge pressure. The gauge pressure is the difference between the absolute pressure and the atmospheric pressure. A positive gauge pressure means the absolute pressure is above the atmospheric pressure. A negative gauge pressure means the absolute pressure is less than the atmospheric pressure. This fluid mechanics video contains plenty of practice problems. This video explains how to calculate the gauge pressure of a two fluid mixture such as oil and water.

great explaination ! thanh you
This channel is saving my life in school right now. Thank you so much for all these physics videos and examples
i got a question.To calculate the gauge pressure why dont we consider too the weight of the water beneath that of oil?
hello sir! thank you for this simple yet understandable tutorial 🙂 i have a question though, when an object is just at sea level (say, an automobile tire with given 24.2 psi) do i still need to convert the given gauge pressure to absolute?
Actual life saver

thanks :DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD =3333
why is Patm @8:28 101.3?
I'm happy to see that you've hit a million subscribers. All the best!
🙂
Love from India.
😍😍
Thanks i love you no homo
um #4 is wrong because pg= pabsolute-patmosphere so the 502 is actually the absolute pressure
Thank you so much
I am so glad i found your channel !!! I cant describe my happiness 🙂 !!!!
Very clear and useful. Thanks
Great video, thanks ^^
You’re the best 👍 great way of explaining. Much better then my professor 👩🏫
Why did u calculate volume of cylinder in btw 4th example to find gauge pressure formulae..pls say…
So the pressure gauge formula is pgh?
thanks for the useful materials. very helpful
So Helpful. THANKS
I love you
Beast mode on
WTH is atm?
Thanks man helped a lot
Why is the gauge pressure called the pressure "above" the atm pressure if it is the pressure "inside" the tank?
where did u get the value of atm in roblem number 4
for question number 4 i think he miscalculated the absolute pressure. it should be 502.25k + 101.3 = 502.35k.
anyone else ?
You're a beast
Our teacher made us memorize a formula. PSI = Height in Inches x Specific Gravity / 27.7" H2O. I'm not sure why though. Can you explain this formula??
Does 4.2 ATM mean 4.2 times the standard 1 ATM? Anyone know?
