1. A turbo pump works at 1200 rpm rotation, with the ability to raise water as high as 200 m as much as 650 liters / minute, which is driven by an electric motor. But because the electric voltage should be 220 volts decreased so that the pump shaft spindle only 1000 rpm with the character of the pump. The pump efficiency assumption is 85%.

a. How much power is needed if the voltage is still normal 220 volt.

b. With the actual condition of the pump turn down to 1000 rpm how much water can be drained if water remains to be raised as high as 200 m.

c. How much water can be raised if the amount of water remains as much as 650 liters / minute.

d. What is the power requirement in the actual condition.

A catrifugal pump is operating at the rotation rate of 750 rpm. Pump is working at the design condition. Water leaves the blade at 40o from the radial direction. Water enters to blade at 80o from tangential direction( offdesign condition). The inner and outher radius of the impeller is 12 cm and 18 cm respectivelly. The width of the impeller is 14 cm. Flow rate of the pump is 0.60 m3/s. Draw the velocity triangles at inlet and outlet of...

1. One pump is not enough to pump water to a very high tank. If you use two pumps (to increase h), how are you going to install them? (a) in parallel (b) in series 2. For turbulent flow of all pipes, friction factor (f) depends on: (a) Reynolds number (Re) only (b) relative roughness (e/D) only (c) both Re and e/D 4. For a pumping system, which tends to cause cavitation? (a) placing the pump close to the source...

A centrifugal water pump is driven at a speed of 1450 rpm. The pump impeller is of radial type and has an average radius of 50 mm at the vane inlet and a radius of 150 mm at the vane exit.

A centrifugal water pump is driven at a speed of 1450 rpm. The pump impeller is of radial type and has an average radius of 50 mm at the vane inlet and a radius of 150 mm at the vane exit. The vane width at inlet and exit are 25 and 10 mm respectively. The vane angles are ?1 = 500 and ?2 = 300. Assuming no prerotation at inlet and neglecting all sources of losses, determine a. the volume...

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.
