2. Water at 60°F is pumped from a reservoir to the top of a mountain through a 6-in Schedule 160 pipe at an average velocity of 12 ft/s. The pipe discharges into the atmosphere at a level 3,000 ft above the level in the reservoir. The pipeline itself is 4,500 ft long. If the efficiency of the pump and the motor driving it is 70 percent and the cost of electric energy to the motor is 8 cents per kilowatt...

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...

A pump that is 80% efficient pumps water from the lower tank to the upper tank at a flow rate of 0.01 m/s through 70 meters of 10-cm diameter pipe. In this system there are two regular, screwed 90 degree elbows and a fully open screwed angle valve. Assume the reservoir exits and entrances are sharp. The friction factor,f, of the pipe is 0.02. What horsepower pump is needed to achieve this flow rate? Use: Pwater = 998 kg/m2; Mwater...

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),...

4.45 A two-tank pump/pipe system has a head requirement of 23.4 ft at a flow rate of 100 gpm. The elevation difference between the fluid surfaces in the tanks is 10 ft. The pump is a Bell & Gossett Series e-80 Model 2.5x2.5x9C operating at 1170 rpm with a 7.5-inch impeller. a. Develop an cquation for the system curve. b. Use a computer program to develop an equation for the 7.5-inch impeller using data read from the pump performance curve...

Problem statement for problems 7-9: Due to the increased water demands in a growing city, a new part of the water system needs to be designed. The Civil Site department tells you that there is a nearby reservoir with a 80 water elevation of 35 ft. You need to design a system that will pump the water to another reservoir with a water elevation of 97 ft. The flowrate through the system must be at least 1200 gpm. Losses in...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...
