Which of the following statements about cavitation is true? Locating the pump below the water surface in the reservoir may not be necessary for avoiding cavitation in centrifugal pumps. Cavitation occurs when the discharge through the pump exceeds the pump's limit as the pump cannot provide energy to the flow (i.e., pump head = 0). When the net positive suction head required (NPSHR) at the pump inlet is too low at the operating discharge of the pump, cavitation may occur. O The Hydraulic Institute indicates that the critical value of the suction specific speed n_ss should be above 8500 to avoid cavitation.
