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 m/s2m/s2. The pressure at the surface of the water will be 145 kPakPa , and the depth of the water will be 13.8 mm . The pressure of the air outside the tank, which is elevated above the ground, will be 87.0 kPakPa .

Part A Find the net downward force on the tank's flat bottom, of area 2.00 m2m2 , exerted by the water and air inside the tank and the air outside the tank. Assume that the density of water is 1.00 g/cm3g/cm3.
