## Homework Statement

You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 145 kPa , and the depth of the water will be 14.2m . The pressure of the air in the building outside the tank will be 92.0 kPA. Find the net downward force on the tank's flat bottom, of area 1.80 m

^{2}, exerted by the water and air inside the tank and the air outside the tank.

## Homework Equations

P=F/A and P=pgh

## The Attempt at a Solution

I plugged in P=1000(3.71)(14.2m)

Then I used that and converted it to kPA to plug in all the pressures combined to find F in the second equation. (52.7+92.0+145)=F/1.80m^2. I got 522. The answer was wrong. Help?
