The diameter of an open-topped tank 1.5 m high increases uniformly from 4.2 m at the base to 6 m at the top. Discharge from the base of the tank takes place through a 75 mm diameter pipe which is 3 m in length. The pipe discharges the water to the atmosphere 1.5 m below the base of the tank. Initially, the tank is fully filled with water. Take f = 0.01. Find the time to empty the tank.
