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),...

11. Water is pumped from a reservoir at a lower elevation to an elevated reservoir by using a suitable pump. The lower reservoir water level have an atmospheric pressure head of I and is at an elevation of 20 ft. while the intake/suction side of the pump is at an elevation of 25 ft. The water is pumped at a rate of 425 gpm in a 6" diameter pipe, friction factor () is 0.017 and the length of pipe is...

Kerosene at 68°F is pumped from a reservoir vented to the atmosphere and delivers it to point B at a low rate of 1,600 gpm. If the pressures at points A and B are measured to be 5 psig and 75 psig, respectively, calculate 2. a. the head loss, hr.(ft) caused by pipe friction (Ggnoring minor losses) in the discharge piping between the pump and Point B, and the hydraulic horsepower delivered by the pump to the water, b. (hp)....

Problem 4 The pumping system shown in the figure below to deliver 3 cfs of 60°F water. The total elevation difference between is 84 ft. The suction line is a 6-inch diameter, 300-ft long cast-iron pipe. The discharge line is 6-inch diameter in an 860-ft long plastic pipe. The suction inlet for the pump is 20 ft above the reservoir. The atmospheric pressure is 14.70 psia. The required NPSH is 7.0 ft. Minor losses include entrance: k, = 0.5, open...

A fire pumper pumps 150 gpm of water from a fire hydrant through 250 feet of 2.5" c=120 fire hose. 50 feet of the hose are on the suction side of the pump with the remaining 200 feet are on the discharge side. The hydrant and the pump are at the same elevation and the pressure in the hydrant is 20 psi. The velocity head in the source main is negligible. The discharge is through a 1.5 inch nozzle at...

Task 1: You were asked to check up the status of the water system. Water at 24 °C is to be pumped from a Lower reservoir with 100 m elevation to another reservoir at a higher elevation 112 m through 150-m-long pipe as shown in Figure (1). The pipe is made of steel, and the diameter ofthe pipe is equal to 30 cm water is to be pumped...

ater to be pumped from a lake to a storage tank in a ranch. Water temperature is 60 F.The clevation of the pipe exit that will feed the tank is 50 ft higher than the lake water surface. It is required that a 4-hour pumping time will feed the storage tank by 1,200 gallons of water. While operating at the required flow rate, the pump will generate a head of 60 n. Coeflicients of minor loss due to filtering, fittings,...
