Three pumps are connected in series. According to pump performance curves, the free delivery of each pump is as follows: Pump 1: 1600 L/min, If the flow rate for this pump system is 2400 L/min, which pump(s) should be shut off? Pump 2: 2200 L/min, Pump 3: 2800 L/min Pump 1 O Pump 2 O Pump 3 Pump 1&2 Pump 2&3

Three pumps are connected in series. According to pump performance curves, the free delivery of each pump is as follows: Pump 1: 1600 L/min, If the flow rate for this pump system is 2400 L/min, which pump(s) should be shut off? Pump 2: 2200 L/min, Pump 3: 2800 L/min Pump 1 Pump 2 Pump 3 Pump 1&2 Pump 2&3 Water enters the pump of a steam power plant at 20 kPa and 50 °C (p = 988 kg/m², & P, = 12.352 kPa) at a rate of 0.15 m'/s. The diameter of the pipe at the pump inlet is 0.20 m. What is the net positive suction head (NPSH) at the pump inlet? 3D 2.14 m 1.95 m 1.76 m 1.52 m 1.36 m

A three lobe rotary pump moves 0.0825 gal of a coal slurry in each lobe volume. The volume flow rate of the slurry (in gpm) for the case where n = 150 rpm is 86.625 gpm O 74.25 gpm O 57.75 gpm O 28.875 gpm 14.44 gpm O A two lobe rotary positive displacement pump moves 0.6 mL of motor oil in each lobe volume. For every 90° of rotation of the shaft, one lobe volume is pumped. If the rotation rate is 550 rpm, the volume flow rate of oil is 0.23 Lpm O 0.66 Lpm O 1.32 Lpm 2.640 Lpm O 3.55 Lpm O
