A catrifugal pump is operating at the rotation rate of 750 rpm.Pump is working at the design condition. Water leaves the blade at40o from the radial direction. Water enters to blade at80o from tangential direction( offdesigncondition). The inner and outher radius of the impeller is12 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 theblade.
Determine;
    b) the blade angles, b1 andb2.
   c)Net head and power of the pump,
   d) Specific speed of the pump
Do not solve the problem without drawing the velocity trianglesat inlet and outlet.
