Cavitation tests are being done on a model pump with an impeller diameter of 20 cm and an inlet pipe diameter of 8 cm. Pumping water at 80 °C and running at 2400 rpm, it is observed to cavitate when the static pressure at the inlet is 80 kPa and the flow rate is 1800 L/min. Find the required NPSH of a prototype pump that is 6 times larger and runs at 1000 rpm while pumping water at the same temperature.

A square bottomed tank measures 25*25*160cm and is positioned with the bottom of the tank 1m above sea level and at 20degreesC. The tank is 90% filled with water and 10% air. A water inlet enters the centre of the tank of 10mm diameter, and no other inlet or outlet is open within the tank. A pump drives water at a starting rate of 450ml/min at 0 Pa lowering to 350ml/min as the pressure increases to 800 kPa. The pump and tank are connected by a 10mm diameter pipe with k=0.15 for all fittings and tubing. It should be assumed this is the maximum flow and pressure provided by the pump. The pump will stop instantaneously once the pressure reaches 800kPa. The relationship between flow and pressure from the pump should be assumed linear. What will be the volume of compressed air inside the tank and how long will it take to fill?
The cylindrical tank in Fig. is being filled with water at20 ° C by a pump developing an exit pressure of 175 kPa. At theinstant shown, the air pressure is 110 kPa and H = 35 cm. Thepump stops when it can no longer raise the water pressure. Forisothermal air compression, estimate H at that time.
