ok so pgh-Patm = P?
please help me its 3am here... i just need someone to actually explain how to get to the answer, because my teacher is a dick. and i hate university with a passion
hmmm maybe this might help better than my sketchy diagram(see attachment)...
i still don't know how to calculate
P="rho"*g*h
but how do i calculate "rho" if i only have the relative density
Homework Statement
Determine the pressure required to make the top of the oil, with height H0=443 mm even with the hight of mercury. The oil has relative density.920 and mercury has relative density13.55. To which side is the pressure applied?
