7-35 A pump is used to fill a tank 5 m in diameter from a river as shown. The water surface in the river is 2 m below the bottom of the tank. The pipe diameter is 5 cm, and the head loss in the pipe is given by h7, = 10 V2/2g, where Vis the mean velocity in the pipe. The flow in the pipe is turbulent, so a = 1. The head provided by the pump varies with discharge through the pump as h, = 20 - (4 x 104)Q2, where the discharge is given in cubic meters per second (m3/s) and h, is in meters. How long will it take to fill the tank to a depth of 10 m? 5 m Pump 5 cm 2 m I River Problem 7.35

Problem A valve is provided at the end of a cast iron pipe of diameter 150 mm and of thickness 10 mm. The water is flowing through the pipe, which is suddenly stopped by closing the valve. Find the maximum velocity of water, when the rise of pressure due to sudden closure of valve is 196.2 N/cm². Take K for water as 19.62 x 104 N/cm² and E for cast iron pipe as 11.772 x 10° N/cm².
