Extracted text: 5.4 The following data refers to a centrifugal pump: Inlet diameter=3 in. Outlet diameter=7 in. Blade angles at inlet and outlet=30° Blade width at inlet=2 in. Blade width at outlet=1 in. If the flow rate is 900 gpm, find the (a) rotational speed, (b) head, (c) power, and (d) pressure rise in the impeller. Assume a, =90°. Ans: N = 2026 rpm; H = 75.3 ft; A, = 22.73 psi %3D
