When a centrifugal pump runs at 1500 rpm, it discharges 0.05 m3 / h of water. The entrance and exit radii of the rotor are given as 0.05 m and 0.15 m respectively, the wing thickness at the entrance is 0.03 m, and the wing thickness at the exit is 0.01 m. The inlet and outlet vane angles are 60o and 45o respectively, and the pump mechanical efficiency is 0.85. In this case; a) What should be the theoretical head of the pump? b) What is the angle of flow between the absolute speed and the peripheral speed at the inlet? c) What power should be given to the shaft of the pump? (ρwater = 1000 kg / m3)

A centrifugal pump delivers water at rate of 0.22 m3/s from a reservoir at a ground level to another reservoir to height 'h' through a vertical pipe of 0.2 m diameter. Both are open to atmosphere. Power input to pump is 90 kW and it operates with 75% efficiency . f=0.004 use g=9.8 m/s2 density=1000kg/m3. Find 'h'.

When operated at N = 1170 rpm, a centrifugal pump, with impeller D = 8in., has a shutoff head ho = 25.0 ft of water.

When operated at N = 1170 rpm, a centrifugal pump, with impeller D = 8in., has a shutoff head ho = 25.0 ft of water. At the same operating speed, best efficiency occurs at Q = 300 gpm, where the head is h = 21.9 ft of water. Fit these data at 1170 rpm with a parabola. Scale the results to a new operating speed of 1750 rpm. Plot and compare the results.

A centrifugal pump lifts water against a head of 36m, the manometric efficiency being 80%. The suction and delivery pipes are both 150mm bore, the impeller is of 375mm and 25mm wide at the outlet; its exit blade angle is 250 and the specific rotational speed is 1320 rev/min. If the total loss by friction in the pipeline at this speed is estimated at 9m, calculate the probable rate of discharge at this speed.
