Question

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 135 kPa , and the depth of the water will be 14.2 m . The pressure of the air in the building outside the tank will be 85.0 kPa .

1.Find the net downward force on the tank's flat bottom, of area 1.80 m2 , exerted by the water and air inside the tank and the air outside the tank.

Explanation / Answer

the net downward force is

F=(P+p*g*h-P building)*A

=(135*10^3 pa+1000 kg/m^2*3.71 m/s^2*14.2m-85*10^3 pa)*1.80m^2

F=1.848*10^5 N
