The surface pressure on Venus is 92.00 atm, and the acceleration due to gravity

Question

The surface pressure on Venus is 92.00 atm, and the acceleration due to gravity there is 0.894 g. Ina future exploratory mission, an upright cylindrical tank of benzene is seated at the top but still pressurized at 92.00 atm just above the benzene. The tank has a diameter of 1.89 m, and the benzene column is 11.00 m tall. Ignore any effects due to the very high temperature on Venus. What total force is exerted on the inside surface of the bottom of the tank? Express your answer using four significant figures. What force does the Venusian atmosphere exert on the outside surface at the bottom of the tank? Express your answer using four significant figures. What total inward force does the atmosphere exert on the vertical walls of the tank? Express your answer using three significant figures.

Explanation / Answer

a) force = PA

        = 92*101325*pi*(1.89/2)^2

      = 2.615*10^7 N

b) Force =2.615*10^7 N as pressure is same.

c) total inward force = 0 N as it will cancel out as exerted from all direction.
