Q3 (40 pts): Water is pumped through a 60-m-long, 0.3-m-diameter pipe from a lower reservoir to a higher reservoir, which has a water surface 10 m above the lower one. When the pump adds 40 kW to the water the flowrate is 0.20 m/s. Assume the following coefficients of minor losses: • Entrance: Kentrance = 0.5 Exit: Kexit = 1 Each elbow: Kelbow = 1.5 • Valve: K= 6 Part A (20 pts) Determine the pipe roughness ε. Part B...

Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kW of shaft power. The free surface of the upper reservoir is 46 m higher than that of the lower reservoir. If the flow rate of water is measured to be0.03 m /s, determine mechanical power that is converted to thermal energy during this process due to frictional effects. 46 m 20 kW Pump 1kW

A pump is used to pump water at 60oF from a reservoir whose surface is 4.0 ft above the centerline of the pump inlet. The piping system from the reservoir to the pump consists of 10.5 ft of cast iron pipe with a diameter of 4.0 in and an average roughness (ε) of 0.02 inches. There are several minor losses: a sharp edged inlet (K – 0.5), three flanged smooth 90o regular elbows (K – 0.3 each), and a fully open flanged globe...

4.) A pumping system is designed to pump from a storage reservoir located at an elevation of 2030 feet. The pump elevation is 2015 feet. The pump discharge flowrate is 4200 gpm and the water temperature is 80˚ F. Between the storage tank and the pump is 25 feet of 12-inch DIP pipe (f = 0.014) with one (1) rounded entrance (Kent = 0.25) and two (2) 45-degree bends (Kbend = 0.20). What is the NSPHA for this system?

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),...

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...
