Water is circulated from a large swimming pool, through a filter, and back to the pool. The power added to the water by the pump is 200 lb-ft/s. The flowrate (in ft/min) through the filter is most likely: Req. pump power = m-gehpumppug.Qhpump = y.Qehpump For obtaining the Darcy friction factor (1), use the following Colebrook equation. 1 eD -2.0log 2.51 3.7 * Revf + K2 exit = 1.0 KZ elbow = 1.5 KĽ valve = 6.0 Kz filter =...
I need just CONTROL VOLUME & ASSUMPTIONS 02. Water at 25 °C is circulated from a large tank, through a filter, and back to the tank as shown in the figure below. The power added to the water by the pump is 271 W Determine the flow rate through the filter. In your solution, follow these steps: Summarize the problem by stating what is given and what needs to be determined State all your assumptions Show the control volume chosen...
Unit Operation and Fluid Homework. Please help! 4. Water is circulated from a large tank through a pipe made of steel and back to the tank as shown in the following figure. The inner diameter of the pipe is 0.03m. The suction line is 20m long, and the discharge line is 40m long. The power output of the pump is 300W, and the pump's efficiency is 75%. The vapor pressure of water is 2300Pa. (a) Use the info in the...
Two large tanks are open to the atmosphere at the top. Water s pumped from the lower tank to the upper tank through a single PVC (smooth) pipe. The relationship between Velocity in the pipe (ft/s) and the pump head (ft) is given. There are no significant minor losses. What is the flow rate, Q (cfs), in the pipe? Pump Coefficients 1.30 sec /ft Pipe Length Inside Pipe Diameter 300 ft 0.250 feet a = 3.24 sec b 107.00 ft...
A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...
ater to be pumped from a lake to a storage tank in a ranch. Water temperature is 60 F.The clevation of the pipe exit that will feed the tank is 50 ft higher than the lake water surface. It is required that a 4-hour pumping time will feed the storage tank by 1,200 gallons of water. While operating at the required flow rate, the pump will generate a head of 60 n. Coeflicients of minor loss due to filtering, fittings,...
8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
(100 points) Water at 25°C is pumped at a rate of 0.075m'/s from a reservoir 20m above a pump to a free discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of 5in diameter cast iron. From the pump to the discharge the pipe is...
