The pump with characteristic curves given in Figure 9.38 is operated as shown in Figure 9.41. The 35-inch impeller is installed. The desired flow rate is 2.0 × 10⁴
gpm. Frictional head loss Fs,1/g from the reservoir to the pump inlet is 7.0 feet, and the fluid is water at 200◦F (93.3◦C). The location of the pump is fixed at 3.0 feet below the level of liquid in the tank. To what pressure must the feed tank be raised to avoid cavitation in the pump?
