A farmer wants to pump water from a river to a very big open storage tank nearby using a 55-m long, 16-cm diameter plastic pipe with 5 threaded 90° regular bends, 5 threaded 45° regular bends, and one fully open gate valve. The water velocity near the river surface is 2.7 m/s and the pipe's inlet is placed in the river normal to the direction of water flow to take advantage of this water speed. The elevation difference between the river and the free surface of the tank is 8.0 m. For the flow conditions inside the pipe, the friction coefficient may be assumed constant at 0.015. The farmer will use a pump with a curve represented by:

h = 23 - 0.84 Q2                where h is in meters and Q in gal/min.

Calculate the volumetric flow rate at which the water is transferred to the tank at these conditions.

A pipe-pump assembly is being considered by a farmer for use in irrigating a field during summer. There is an underground water well that is 250 ft deep. The well is an open-hole type in which the free surface of water is about 8 ft below grade. To ensure that one of the pumps will operate for only a few hours per day, the farmer will fill a 2500-gallon tank in 4 hours, which will provide enough water for 2...

A pump will be used to convey water from a lake into a pressurized storage tank for a secluded cabin vacation house. If 1000 gallons of water must be delivered in 10 minutes or less, will a pump that adds 3 hp to the water be sufficient? Explain and support your answer with calculations.    Assume 2 atm for the pressurized tank, and 20 ft difference in elevation from lake to water surface level in pressurized tank. ANSWER: 3 HP...

Hot water in an open storage tank at 82.2°C is being pumped at a rate of 0.379 m3/min from the tank. The line from the storage tank to the pump suction is 6.1 m of 2-in schedule 40 steel pipe and it contains two elbows. The water discharge line after the pump is 61 m of 2-in pipe and contains two elbows. The water discharges to the atmosphere at a height of 6.1 m above the water level in the...

An industrial pump is to be used to supply water from Lake Bonno to an agricultural field located 500 m away from the lake, and at an elevation of 20 m above the surface of the lake. If the horse-power of the pump is 45-hp, what is the discharge that can be delivered by using a pipe of diameter D = 0.4 m and a friction coefficient of f = 0.015? Neglect all minor losses. Is the flow laminar or...

City water will be cooled in a heat exchanger by sea water entering at 15°C. The outlet temperature of the sea water is 20°C. City water will be recirculated to reduce water consumption. The suction line of the pump has an inner diameter of 154 mm, is 22 m long, and has two 90° bends and a hinged check valve. The pipe from the pump to the heat exchanger has an inner diameter of 127 mm, is 140 m long,...

Water is pumped by a motor-pump unit from a lake to a storage tank 17 m above at a rate of 120 L/s. The storage tank is open to the atmosphere. The motor consumes 25 kW of electric power and the motor effciency is 95%. Disregarding any changes in kinetic energy of the water, determine (a) the overall effciency of the pump-motor unit, (b) the effciency of the pump and (c) the shaft power supplied by the motor to the...

A pump is used to deliver water from a large reservoir to another large reservoir that is 20 m higher. The inlet of the pipe is submerged in the one reservoir and the exit is just above the surface of the other reservoir. If the friction head loss in the 200-mm-diameter, 4-km-long pipeline is 2.5 m for every 500 m of pipe length, determine the required power output of the pump so the flow is 0.6 m3/s.

A pump delivers water (r= 1000 kg/m3, µ= 0.860x10-3 kg/m·s) from one reservoir to another reservoir through 120 m of 0.05 m diameter pipe. Volumetric flow rate in the pipe line is measured with venturi meter. Throat diameter of venturi meter is 38 mm and pressure drop in the venturi meter is 156.9 kPa.The surface of the pipe is rough e/D=0.0001. Calculate the power of the pump required for the water–transfer. See the figure below for several pipe– fittings installed...
