A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...
A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
Question 3: Water is to be pumped from one large, open tank to a second large, open tank. The water surface of the first tank is 5 ft lower than the water surface of the second tank. The pipe diameter throughout is 4in. The total length of pipe is 300ft. The friction coefficient is 0.02. The pump with the performance curve given in the figure is suggested by the engineer. With this pump, what would be the flow rate between...
Please show detailed work and write clearly.Thank you. A chilled-water system requires a 100 gal/min pump with 40 ftWG of head. Select the most appropriate pump from the pump curves in the figure below. State the efficiency, motor power input, impeller size, and NPSH requirement for your selection.

A pump delivers water at 200C between a reservoir and a water tank that is 75[ft] higher than the reservoir. The suction side of the system consists of a cast iron pipe of 1[ft]diameter with a strainer (Ks= 2.5) and four 90-degree bends at R/D= 5. The discharge side of the system includes a 1000[ft] long commercial steel pipe with 12” diameter followed by a gate valve. The NPSH required for the pump is 10[ft], and the design discharge is...
A water pump is required to lift 800 liters of water per minute from a well 10 meters deep to an elevated tank 5 meters above ground level. a) How much work does the pump do in a time of 1 min.? b) What is its power output in Hp? c) If its efficiency is 90%, what is its power input in Hp? d) How much work is lost if the pump operates for 1 hour
0.5 in 10-72. The copper pipe system, which transports water at 70°F, consists of two branches. The pipe for branch ABC has a diameter of 0.5 in. and length of 8 ft, whereas the pipe for branch ADC has a diameter of 1 in. and length of 30 ft. If a pump provides an inlet flow at A of 67.3 gal/min, determine the flow in gal/min through each branch. Take e-80(10-6) ft. The system is in the horizontal plane. Include...
Problem 5: The 28-in-diameter pump in the Figure at 1170 r/min is used to pump water at 20°C through a piping system at 14,000 gal/min. (a) Determine the required brake horsepower. The average friction factor is 0.018. (b) If there is 65 ft of 12-in-diameter pipe upstream of the pump, how far below the surface should the pump inlet be placed to avoid cavitation? Given that the water at 20 °C has a specific weight of 62.4 lbf/ft and vapor...
4. A fire truck pump system is shown. Water is pumped from a reservoir to a surge tank and then out an exit pipe and nozzle to shoot a water jet vertically into the air. The water surface in the surge tank is exposed to air pressure at P 827 371 N/m2 (gage). The pump efficiency is assumed to e 80% a) Calculate a numerical valuc for the water velocity at the pipe exit at station 4. b) Calculate a...
Water at 160° Fis drawn at the rate of 400 gal/min from a vented tank into the 2-in Sch 40 suction line of the pump made of steel. The suction line has a total length of 10 ft. the discharge line elevates the water 30 ft to the level of the large heat exchanger. The discharge line has a total length of 40 ft. The system contains: 2 standard elbows, 1 swing check valve, and 4 open gate valves. Assuming...
