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...

The system below shows a simplified schematic of an oil transfer system between tanks, from left to right: L L The oil specific gravity is 0.77 and its viscosity is 2.7 [cP). The pipes are horizontal and coaxial (neglect difference in height between suction and discharge). The tanks are closed but vented so that they are at atmospheric pressure ([atm]). Assume for simplicity that the liquid level in each tank is 2.5 (m) above the level of the pipes (in...

A water intake at a pump storage reservoir (the figure) has a cross-sectional area of 0.642 m. The water flows in at a speed of 0.480 m/s. At the generator building, at distance D = 119 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.67 m/s.

7.14 The pump in Fig. 7.20 delivers water from the lower to the upper reservoir at the rate of 0.057 m3/s. The energy loss between the suction pipe inlet and the pump is 1.83 m and that between the pump outlet and the upper reservoir is 3.66 m. Both pipes are 6-in Schedule 40 steel pipe. Calculate (a) the pressure at the pump inlet, (b) the pressure at the pump outlet, (c) the total head on the pump, and (d)...

Q4: The pump is used to deliver of water from a river to a storage reservoir. The four pipes are connected in series of Inverse L shape which means the first pipe in vertical direction and others in horizontal direction. The first pipe in vertical position of 500m length of 150 mm diameter cast iron pipe, the second pipe is bend at 90' with a radius of 0.75m, the third pipe in horizontal direction of 100m length of 160mm diameter...

1 A pump delivers water from the lower reservoir to the upper reservoir at a rate of 60 L/s. Both the suction and discharge pipes are DN 150 schedule 40steel pipe. The length of the suction pipe leading to the pump is 3.5 m, and 7 m of discharge pipe extend from the pump outlet to the upper tank. There are three standard 900 elbows and a fully open gate valve. The depth of the fluid level inside the lower...

(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...
