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?
When a pump with a suction and discharge pressure of 125 kPa and 409 kPa are used, the flow rate is 30L/s into a pipe with a diameter of 4 cm. Approximately 10cm in diameter, the suction diameter. What is the energy added to the water by the pump in meters

We have a tank (large enough to neglect the velocity of the fluid surface in the tank v1 =0). The tank contains water at a mevel of 15 meters. The tank is enclosed and the air space above the water is at 5 atm. The exit of the tank consists of 25 meters of 2 cm diamter pipe with d/D = 0.0004. It exhaust to the atmospere at 1 atm. What is the exit velocity?
Include a fre body diagram Water enters a pump at 350 kPa at a rate of 1 kg/s. The water leaving the pump enters a turbine in which the pressure is reduced and electricity is produced.

Water at 20°C is pumped at a constant rate of 9 m3/h from a large reservoir resting on the floor to the open top of an experimental absorption tower. The point of discharge is 5 m above the floor, and friction losses in the 50-mm pipe from the reservoir to the tower amount to 2.5 J/kg. At what height in the reservoir must the water level be kept if the pump can deliver only 0.1 kW?The value of alpha we should use for the kinetic energy term is?
