The inlet pressure to a piping system is 440 kPa. The inlet pipe diameter is 0.6 m. What is the velocity of the flow of water and discharge at the inlet?
Saturated water at 310K is being pumped from a tank to an elevated tank at the rate of 7L/s. All of the piping is in 5-in. schedule 40 steel pipe. If the 2 fittings used is 90° ell standard long radius, The pump has an efficiency of 80%. Calculate the kW power needed for the pump.
The volume flow rate of water that recirculates from the blade outlet to the impeller is estimated to be 0.4524 ft^3/min, and the losses through the shaft sealing is negligible. The hydraulic and mechanical efficiency of a centrifugal pump are 95% and 93%, respectively. If the pump delivers water a flow rate of 12 ft^3/min, calculate the pump efficiency in %.
4. Three storage tanks A, B and C are connected to a piping system as shown in Fig. The flow rate of water in the pipe which is connected to tank B is 0.06 m³/s. Determine the flow rate in the other two pipes and then calculate the level of the water in tank B relative to ground level. Friction factor, f = 0.01.

The impeller of the centrifugal pump is 350 mm diameter, and the width of the blade passages at outlet is 18 mm. A pump, which runs at 16.6 rev/s, is mounted so that its centre is 2.4 m above the water level in the suction sump. It delivers water to a point 19 m above its centre; the friction loss in the suction pipe is 68 Q² meter and that in the delivery pipe is 650 Q² meter where Q in m3/s is the rate of flow. The blades themselves occupy 5% of the circumference and are backward facing at 35° to the tangent. At inlet, the flow is radial and the radial component of velocity remains unchanged through the impeller. Assuming that 50% of the velocity head of the water leaving the impeller is converted to pressure head in the volute, and that friction and shock losses in the pump, the velocity heads in the suction and delivery pipes are negligible, calculate the following: The flow rate, m3/s, of the pump. Manometric efficiency, in %, of the pump.
The task is to to transfer the fluid from the source towards the tank (TANK A) lying on an elevated platform as shown. The goal is to fill up that 16.49 m by 2.23 m by 6.36 m tank (TANK A) within 11.5 mins (from empty to full). Your budget is limited to 605,000 pesos. Head loss on pipe due to friction is 1.23 meters per 1 meter of pipe. Because it's Fluid Machinery and not Engineering Economics, it's ok for your design to exceed the budget BUT YOU HAVE TO JUSTIFY IT.

A pump is used to take water out of a large lake and deliver it to a farm to be used for irrigation. The pump location is illustrated in the figure below, where the suction side of the pump (also called the pump intake) is 3 m above the water surface in the lake and the vertical intake pipe has a diameter of 150 mm.
