If the flow from Ato B is 5 cfs. a) Determine the head loss in feet in PIPE 1 and PIPE 2 b) Determine the head loss in feet in PIPE 5 c) Determine the flow in the upper branch pipe Q2 in cubic feet per second d) Determine the total head loss in feet between the inlet A and the outlet Darrow_forwardDischarge water at a flow rate of 2.5 m3/s through a pipe flowing into a turbine to generate electricity. The inlet pipe has a diameter of 1 m. The outlet has a diameter of 1.5 m. The gauge installation at the inlet is 2 m higher than the outlet gauge. The pressure at the inlet and outlet of the turbine is shown. in the picture If losses from the piping system are not taken into account, find out how many watts of power this turbine will produce, given that the efficiency of this turbine is 80%.arrow_forward1. The figure shows a pump that draws 840 L/min of crude oil (s= 0.85) in an underground storage drum to the first stage of a processing system; a) If the total energy loss in the system is 4.2 N m/N of oil flow, determine the power transmitted by the pump to the fluid. b) If the energy loss in the steel suction line is 1.4 N m/N of oil flow, determine the pressure at the pump inletarrow_forward
- A large container filled with water and uncovered for use in fighting fires in an ethylene production plant. Water from this tank is pumped into the nozzle when needed use. This fire suppression system is designed to be able to transmit 1890 L/min of water at a pressure of 15 bar (relative pressure). If we ignore the difference in height between the water level in the tank and pump, there is no change in diameter of pipe and nozzle, pump efficiency is 70%. Ask how much work (hp) is required to the pump to achieve the desired pressure and flow would like?arrow_forwardDuring the daytime, water is drawn from an upper reservoir and is run through a turbine on its way to a lower reservoir in order to produce power. The pipe is 300 feet long and has a 2.0-foot diameter. It is constructed of commercial steel which has a roughness height of = 0:0018 in. Find the power extracted by the turbine if the downward volume áow rate is 20,000 gallons per minute.(Recall that H2O = 1:94 slugs/ft3, H2O = 2:4 10^-5 slugs/fts.)

(Hint: plot power vs. flow rate in order to answer this question.)arrow_forwardA pump test reports the section pressure at a pump inlet to be 20 kPa below atmosphere. The discharge pressure at a point 1,025 mm above the inlet is 520 kPa. If the volume flow rate of water in the system is 87 L/min, calculate the power, in Watts, delivered by the pump to the fluid.arrow_forward
- The water taken from A reservoir is transferred to B by passing through a turbine with a 600 mm pipe. Calculate the power (W) generated by the turbine as the total irreversible load in the system is 10 m, the height between the A and B source is 60 m, and the volumetric flow is 700 L / s.arrow_forwardA pump is required to transfer water at the rate of 350 kg/s from an open sump to an open storage tank located 30m above the pump. The sucLon pipe is 350mm in diameter and 12m in length and the delivery pipe is 550mm in diameter and 40m in length. Calculate:(a) The maximum height at which the pump may be placed above the sump, so that pressure at the inlet is not less than -80 kPa (gauge) (b) the energy to be supplied by the pump per unit mass of water transferred (c) The input power required by the pump, which is 60 % efficientarrow_forwardA 5 kW electric motor driving a pump has an efficiency of 85%.

Answer the following additional questions: 2 -If the combination of pump and motor is 80% efficient, how much electrical power (kW) is needed to drive the pump? 3 -, in order to avoid vapour lock, the pressure in the pipeline must always be above the vapor pressure of the crude oil, what is the maximum permissible elevation of point 3 relative to point 4? 4 -If the flow in the pipeline were at the upper limit of being laminar, what pump exit pressure would then be needed?

The figure below shows the elevations and pipe connections. It is desired that the jet water of the fountain reaches a height of at least 2.5 m from the nozzle outlet. As for the tank, it is elevated in order for it to distribute water using gravity. The specifications of nozzle, suction and discharge pipes are given in the table below. Assuming negligible minor head losses, what is the minimum power input to the pump in kW? Take pump efficiency to be 88% and motor efficiency, 95%.
