A centrifugal pump of 1.75 diameter runs at 210 rpm and pumps 2000 litres of water per second. The angle which the vane makes, at exit, with the tangent to the impeller is 30°. Assuming radial entry and velocity of flow throughout as 2.75 m/sec. Determine power required to drive the pump. If manometric efficiency of the pump is 75%, find average lift of the pump.

A centrifugal pump with a 735 mm diameter impeller runs at 1979 rpm. The water enters without whirl, and α2 = 30ª. The actual head produced by the pump is 17 m. Find the hydraulic efficiency when V2 = 6.7. Express your answer in decimals.
A centrifugal pump delivers 0.071 m3/s of water against a head of 7.6-m at 1450 rpm and requires 6.7 kW. If the speed is reduced to 1200 rpm calculate the head, assuming the same efficiency.
A plant has installed a single suction centrifugal pump with a discharge of 68 m3/hr under 60 m head and running at 1200 rpm. It is proposed to install another pump with double suction but of the same type to operate at 36.27 m head and deliver 90 m3/hr. Determine the speed of the new pump. What should be the new impeller diameter if the diameter of the original pump is 140mm?
Pumps: A centrifugal pump having 4 stages in parallel, delivers 18 kiloliters/min of liquid against a head of 25 m. The diameter of the impellers being 24 cm and the speed of 1800 rpm. A pump is to be made up with a number of stages in series of similar construction to that of the first pump to run at 1250 rpm and to deliver 15 kiloliters/min against a totalhead of 250 m. Find the diameter of the impellers and the number of stages required in this case. Answer: D = 46.63 cm, n = 6 stages

A centrifugal pump discharging 10 lps against 25 m of head and operating with an efficiency of 60% requires 4.1 kW at 1000 rpm. What is the theoretical discharge if the speed is increased to 1500 rpm assuming the efficiency remains constant? What is the theoretical head and kW at 1500 rpm?.
The MITL ME laboratory has installed a double-suction, three-stage, centrifugalpump with a discharge of 330 gpm under 200 ft head and running at 1200 rpm.
