The system of Fig C11.4 is designed to deliver water at 20C from a sea-level reservoir to another through new cast iron pipe of diameter 38 cm. Minor losses are _K1 0.5 before the pump entrance and _K2 7.2 after the pump exit.
(a) Select a pump from either Figs. 11.7a or 11.7b, running at the given speeds, which can perform this task at maximum efficiency. Determine
(b) The resulting flow rate;
(c) The brake horsepower; and
(d) Whether the pump as presently situated is safe from cavitation.
