Determine the torque needed to turn the impeller

Reference no: EM13528830

A centrifugal pump is used to pump water from ariver. The absolute velocity V2 = 82ft/s is at an angle of 25 degrees to theradial direction. The impeller's thickness is of 1.2 in and r2= 0.86 ft and rotates at a speed of 1250 rpm.

1) Draw the velocity diagram at the flow exit.

2)Determine the torque needed to turn the impeller?
