![Ex. 2.11 A pump delivering 230 Ips of water whose absolute viscosity is 0.0114 Poise has a
300-mm diameter suction pipe and a 254-mm diameter discharge pipe as shown in the
figure below. The suction pipe is 3.5 m long and the discharge pipe is 23 m long. The water
is delivered 16 m above the intake water level. Considering the head losses in fittings and
valves, find the head which the pump must supply. If the motor brake power of the driving
motor is 75 kW, what is the efficiency of the pump? Assume the pipe material as cast iron.
Given: A figure showing a pumping installation
Q= 230 Ips
D = 300 mm D = 254 mm
H = 0.0114 Poise = 0.00114 Pa-s
BP = 75 kW
