A pump move warm water at 120F from a reservoir open to atmosphere. The pipe is 6" diameter cast and has a standard 90 degree elbow and a fully open gate valve. The pump draws water from a pipe submerged below the water surface. The pump is 10 feet above the reservoir surface, and there are 20 feet of pipe in the inlet section. If the flow rate is 1,650 gpm, what is the NPSHA at the pump inlet?

35. (a) A reservoir A discharges water to a lower reservoir B through a 3600 m long pipe of diameter 600 mm. The flow is due to gravity and the difference in surface water levels in A and B is 13 m. Reservoir A is now required to supply water also to a third reservoir C, the water surface of which is 15 m below that of A. The discharge to C is to be made from a 1200 m...

The fresh water behind a reservoir dam is 15.0 m deep. A horizontal pipe 2.50 cm in diameter passes through the dam 7.5 m below the water surface, as shown in the figure. A plug secures the pipe opening. Find the magnitude of the frictional force between plug and pipe wall. The plug is removed. What volume of water flows out of the pipe in 2.0 hours?

Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole for a) a sharp edged entrance followed by threaded 90° bend and then a 3.5m length of wrought iron pipe and finally a fully open Globe Valve b) redo a) for the ideal case with no viscous losses

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...
