Question: A certain tank has a circular bottom area A = 20 ft2. It is drained by a pipe whose linear resistance is R = 150

A certain tank has a circular bottom area A = 20 ft2. It is drained by a pipe whose linear resistance is R = 150 m-1sec-1. The tank contains water whose mass density is 1.94 slug/ft3
a. Estimate how long it will take for the tank to empty if the water height is initially 30 ft.
b. Suppose we dump water into the tank at a rate of 0.1 ft3/sec. If the tank is initially empty and the outlet pipe remains open, find the steady-state height and the time to reach one-third that height, and estimate how long it will take to reach the steady-state height.
