Q5/ A centrifugal pump impeller runs at 1500 rpm & has internal & external diameters of 0.2
m & 0.4 m respectively. Assuming constant axial velocity Va1= Vaz= 2.8 m/sec & the vane
angle at exit B2 = 30°. Calculate:
%3D
1- Angle of the absolute velocity of water at exit?
2- Inlet vane angle?
3- If the efficiency & inlet power of the pump 90% & 47 KW, find the pump outlet power?
