A catrifugal pump is operating at the rotation rate of 750 rpm. Pump is working at the design condition. Water leaves the blade at 40^o from the radial direction. Water enters to blade at 80^o 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 the blade.

Determine;

b) the blade angles, b₁ and b₂.

c)Net head and power of the pump,

d) Specific speed of the pump

Do not solve the problem without drawing the velocity triangles at inlet and outlet.

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....

A DC shunt motor drives a centrifugal pump at a speed of 1000 rpm when the terminal voltage and line currents are 200 V and 50 A, respectively. Given the armature resistance, Ra = 0.1 ohm and field resistance, Rf =100 ohm. Design a circuit which the speed of the motor can be controlled by using the added resistance method to the armature circuit and the maximum starting current is 120 A. Next, if the added resistance in the designed...
