Hey thanks for this video, it is very consistent and affective. It's better than other videos. The last video I watched had 100k+ views or something but had a contradiction within it which made it confusing. I wish I came across this video first hopefully you got more views, I appreciate the content thank you.

Sir for my problem, at the end of the question they stated that the local atmospheric pressure to be 95.5 kPa. They still asked to determine the gage pressure though. So is this value just meant to throw the students off or am I to consider P2 as 95.5 kPa? Edit: This was a past assignment and just stumbled upon it while reviewing. I do not know if I actually got it right as I considered P2 as 95.5 kPa.
@engineeringdeciphered
@engineeringdeciphered 3 года назад
You were right to begin with. You don’t need that value to calculate the gage pressure. You would need it to calculate the absolute pressure.

i have a question : to use or apply the rule that we all know that any point at the same horizontal plan has the same pressure ;; is the point has to be in the same material or liquid?? or it could be different???

but in our version it gave us the atm pressure value. do we need to take into account?
@engineeringdeciphered
@engineeringdeciphered 3 года назад
Yes, if it is asking for the absolute pressure. You would have that value where I have the 0. But if it is asking for gage pressure, you wouldn’t use that, even if it is given.

@Darwin-bg1pm 3 года назад
My problem specified that P2=Patm so Im good. but what if it didnt specify or didnt put gauge pressure instead, it says "determine air pressure" instead of gauge pressure, would P2 = Patm ?
@engineeringdeciphered
@engineeringdeciphered 3 года назад
Correct, if it is open, the pressure at that open area would be the atmospheric pressure.
