(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)...
2 Underground water is to be pumped by a 80 percent efficient 10-kW submerged pump to a pool whose free surface is X m above the underground water level (see Figure 2). The diameter of the pipe is 10 cm on the intake side and 8 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the...
Q4. A pump draws water from a large reservoir and delivers it to another reservoir whose water surface is 10 m higher than the pump centreline and that the pump is 1.5 meter above the suction reservoir. The total suction and deliver pipe used is 21.1 m in length, 9 cm in diameter and has a Darcy friction factor f0.0339. The pump operates at 750 rpm and its characteristic performances are given in table below: Q (m3 s H (m)15...
Underground water is to be pumped by a 78 percent efficient 5-kW submerged pump to a pool whose free surface is 30 m above the underground water level. The diameter of the pipe is 7 cm on the intake side and 5 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic...
Q5. A pump is located 2 m below the water surface in a reservoir as shown. The piping between the pump and the reservoir consists of 3 m of 150-mm-diameter ductile iron pipe of 0.2 friction Coefficient. The valves and bends between the source reservoir and the pump are estimated to have a total local loss coefficient of k=50 (hikV2/2g). The water in the reservoir has a temperature of 25°C and the atmospheric pressure is 101.3 kPa. What is the...
diameter as shown in the A pump is used to deliver water from an opened reservoir through a pipe with 4 cm of figure. The water flows through the system with a rate of 360 m hour and d head loss is measured to be 7 m, calculate the useful power of pump of water in reservoir while point 2 is set correction factor to be 1.0 scharged to the atmosphere. If the total in unit of Pa. Point 1...
A house is located near a freshwater lake. The homeowner decides to install a pump near the lake to deliver 25 gallons/min (0.0557 ft3/s) of water to a tank adjacent to the house to be used for plumbing and the lawn. For the systenm shown n the figure below 1. Determine the power that the pump must supply to the fluid i order to maintain the flow rate, specify your answer in Horsepower 2. State how much power must be...
Pump Water To double the outflow of a reservoir, a pump is added as shown in the Figure above. The head in the reservoir is H 5 m, the pipe diameter is D-0.3 m and the the total length of the pipe system system is L-90 m. For reference, the density of water is given by Pwater 998.2 kg/m3 and the acceleration due to gravity is given by g 9.81 mls2 Please provide your answers to 2 significant figures. (a)...
2. Do Problem 5.118 from the textbook. (Statement: A pump moves water horizontally at a rate of 0.02 m/s. Upstream of the pump where the pipe diameter is 90 mm, the pressure is 120 kPa. Downstream of the pump where the pipe diameter is 30 mm, the pressure is 400 kPa. If the loss in energy across the pump due to fluid friction effects is 170 N.m/kg, determine the hydraulic efficiency of the pump.)
b= 2.5 meters is the answer (how) It is desired to pump 30 kg/s of water from a lake at 20 C to the top of a building which is 70 m tall. The pipe from the pump discharge to the top of the building is 70 mm in diameter, has a total length of 100 m, and discharges to the atmosphere at the top of the building. a) Assuming the pipe is commercial steel, what must the pressure be...
