1 atm = 101300 Pa = 101300 N/m2

density of water = 1000 kg/m3

The tube is filled with water. A1 = 0.05m^2 and A2 = 0.08m^2. Two pistons apply different forces to the water in the tube so that the water in the right side of the tube is a height h = 0.43m above the height of the water in the left side of the tube. If F2 = 138 N what is F1?

********

I know general equation is F/A equals pressure.

Well, I wanted to do F1/A1=F2/A2... but the fact that both sides of the tube are not level gives me a problem.

It's probably a simple concept, but I'm not seeing it. HOw do I set it up to account for the height=.43m factor?
