Am i wrong in assuming that volume is of cylinder?

P(below)= P(above)+density*gh

P(above) would that be considered atmospheric pressure?
That's what I would assume.

Sorry I confused things earlier by dropping the atmospheric pressure. It is needed here for a static liquid.

How would I calculate that? Force=Pressure/Area

Calculate what? You are given Pb and you know Pa.

See post #27. That's what we've been talking about.

I understand the equation, but i don't know how to come up with a number for Pa, to plug into the equation.

Hint: What's atmospheric pressure in units of atm? :tongue:

(You can also express atmospheric pressure in standard units.)

1 atm= 101300 Pa....thats it?

Sure. Note that the pressure at the bottom is given in units of atm.
