A pump draws water from a well through a 153mm vertical tube. The pump has a horizontal discharge tube of 102mm in diameter, which is 3.23m above the water level in the well. While the flow rate is 0.035m³ / s, pressure gauges near the pump at the inlet and outlet indicate -31.44Kpa and 176.51Kpa respectively. The discharge indicator is 1.91 m above the suction indicator. Determine the power supplied by the pump. Use for the questions below g = 9.79 m / s²; μ = 8.0 x 10 -4 Pa.s; ρ = 996 kg / m³

3. A pump draws water at 15°C from a well through 10 m of 3 inch sch 40 steel pipe. The pump is 7 m above the water level in the well. The pump discharges the water -horizontally through 30 m of 3 inch sch 40 steel pipe to a sprinkler. There is one check valve (ball type), and three 90° standard elbow installed at various places in the system. The pressure into the sprinkler should be 500 kPa and...

A water supply system draws from a river at an elevation of 800-feet and delivers the water to a storage reservoir at elevation 820-feet. The supply pipeline is a 1000-foot long, 10-inch diameter, cast iron pipe. A single pump with the pump characteristic curve in Figure 1 is used to fill the reservoir. Determine: a) Sketch the system described in the problem statement. b) Inlet and outlet minor loss coefficients, cite your source of minor loss coefficients. c) The roughness...

Problem #1: A 4.5 kW pump operating at steady state draws in liquid water at 1 bar, 15 °C and delivers the water at 5 bar to a location whose elevation is 6 m above that of the inlet. There is no significant change in velocity between the inlet and exit, and the local acceleration of gravity is 9.8 m/s? Would it be possible to pump 5.5 m in 10 min or less? Explain. (25 pts)

(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...

You need to pump water at 20 C from an open reservoir at flow rate of 1.4 x 10^-3 m3/s through a pipe with an inside diameter of 0.03m, using a centrifugal pump having an (NPSH)aq =2.5 m and the equivalent length on the suction side is 3m. There are several minor losses: four standar 90 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the Entrance. What is the the maximum distance above the...
