A pump 254mm suction pipe and a 127mm discharge pipe is use to deliver 52L/s of water. The suction gage reads 120mmHg vacuum and the discharge gage located 100 cm above the suction gage which reads 108 kPa gage. Find the ff: (a) TDH in meter, (b) water power in kW, (c) If the power of the driving motor is 15 Hp, what is the pump efficiency? Answers: 14.45m; 9.978hp, 65.85%
