A centrifugal water pump runs at 1,800 rpm and has an out5ide radius of 12 in. (

Question:

A centrifugal water pump runs at 1,800 rpm and has an out5ide radius of 12 in. ( β0 = 170°) , an inside radius of 4 in. ({βo = 160°) , and an impeller thickness (width) of 2 in. at r = ri and ~ in. width at r = r 0 • Determine the pump flow rate for a shockless entry (i.e., a I = 90°) and the exit angle a0
