For the impeller of Problem 10.1, operating at 750 rpm,

determine the volume flow rate for which the tangential

component of the inlet velocity is zero. Calculate the theoretical head and mechanical power input.

 Consider the geometry of the idealized centrifugal

pump described in Problem 10.11. Draw inlet and outlet

velocity diagrams assuming b 5 constant. Calculate the inlet

blade angles required for “shockless” entry flow at the design

flow rate. Evaluate the theoretical power input to the pump

at the design flow rate.
