1. An axial flow water pump is based upon the free-vortex design. The mean diameter velocity diagram has an axial inlet with a flow coefficient of 0.3 and a work coefficient of 0.208. The tip diameter to mean diameter and the hub diameter to mean diameter ratios are 1.25 and 0.75 respectively. The blade velocity at the mean diameter is 60 m/s. Find and draw the velocity diagrams at the mean, hub and tip diameters. Show all velocities and angles on the velocity diagrams. .`
