Course work. Design of a centrifugal pump.

Initial data:
Flow through the pump Q = 50m3 / hr;
Pump head H = 12,5 m;
Revolutions 1450ob / min;
Excessive pressure on the PBX input = 1.013 * 105Pa;
Density of the liquid γ = 1000;
The dynamic viscosity of the fluid μzh = 1.01 * 10-3;
elasticity Vapor Pressure P = 2.314 * 103Pa;
Normal thickness of the blade:
- At the entrance of δ1 = 0.005;
- Output δ2 = 0.01.
