Homework Equations



P2=P1+pgh

The Attempt at a Solution



I thought you would just plug in the pressure in pascals to p1 and add [(1000 kg/m3)(9.8m/s2)(sqrt 2)]?
 
Physics news on Phys.org
Okay find out the pressure in chamber 1. Pressure=force/area.
Did this help?
 
So the answer is just 1.3x10^5 divided by 2?

Why?
 
No, 1.3x10^5 is pressure in chamber 2. Use the formula given to you in the question to calculate the pressure in chamber 1. You know the area of chamber 1 and you have calculated the pressure for chamber 1 so rearrange the formula pressure=force/area to give you the force.
