5.1.6. A centrifugal pump is being tested in a laboratory. The inside and outside radii of the impellers are 7.5 cm and 15.0 cm, respectively. The width of the impeller vanes (or flow opening height) varies from 5 .0 cm at intake to 3.0 cm at outflow. If the measured flow rate is 55 liters/sec, what is the pump speed (in rpm) and the power input to the pump (in kW)? Assume a shockless entry (a
i = 90°), an exit flow angle of 22.4°, and b
i = 150°.
please show the solution with sketch digram
