Prob-2 What power must be supplied by the pump to the flow if water (T -20°C) is pumped through the 300 mm steel pipe from the lower tank to the upper one at a rate of 0.314 m?s? Situation: Properties: Water is pumped through a steel pipe from one tank to another From Table 10.6 K-003: Ks-035 Kg - 10. D-300mm. L-140m. Q=0.314 m/s. Water 20°C). Table A = 10-m. 81 - 200 m. = 235m. Elbow radius is 300...
4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...
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 of the pipe is equal to 30 cm. Water is to be pumped by a 72% efficient motor-pump combination that draws 33 A of...
A pump carries water at a temperature of 30 ° C from one tank (A) to another (B). The diameter of the pipe leaving tank A and reaching the pump is 4 inches. The diameter of the pipe leaving the pump and reaching tank B is 3 inches. The pump motor increases the fluid pressure by 3 kgf / cm2 (ΔP), and generates a power per unit of mass of 300 J / kg. Calculate the height difference (ΔZ) between...
What horsepower must be supplied to the water to pump 2.5 cfs at 68°F from the lower to the upper reservoir? Assumne the pipe is steel. Sketch the hydraulic and energy grade lines. (See attachment for more details and sketche) 5-8 What horsepower must be supplied to the water to pump 2.5 cfs at 68 F from the lower to the upper reservoir? Assume the pipe is steel. Sketch the hydraulic and energy grade lines. ElevationI50 ft Elevation 100 n...
A pump transmits water at 10 °C from the reservoir to an elevated tank L2= 150 m as shown. The loss coefficient in Elevation = 190 m Elevation = 185 m each bend is 0.4 and loss in the pipe Water entrance is Ke = 0.5. There are no L=100 m loss at the pipe exit at the elevated Elevation D -20 cm tank. The pipelines are made of steel. -150 m -- Elevation - 145 m State your assumptions...
Prob-2 If the flow of 0.10 m/s of water is to be maintained in the system shown, what power must be added to the water by the pump? The pipe is made of steel and is 20 cm in diameter. Use table 10.4 and A5 for ks =? and V =? Elevation = 13 m Elevation = 10 m Water T= 10°C 40 m 40 m
Prob-2 If the flow of 0.10 m3/s of water is to be maintained in the system shown, what power must be added to the water by the pump? The pipe is made of steel and is 20 cm in diameter. Use table 10.4 and A5 for ks =? and v=? Elevation = 13 m Elevation = 10 m Water T= 10°C 40 m 40 m
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...
what is the velocity head at the inlet pump? Find the value of head loss (consider entrance, friction, elbow and valve losses). Also, find pressure at the inlet pump water is at 80 degrees C Water is being pumped from the tank at a rate of 475 L/min -115 m E Pump Globe valve fully open DN 65 Schedule 40 steel pipe 1.40 m 0.75 m Standard elbows (2)
