Your father installed a pump to draw water from a well to your house water tank. The desired discharge is 70 Ls. He bought a pump (Pump 1) which delivers 2 kW of power to the water from a nearby hardware store. a) Evaluate whether the pump is adequate to deliver the desired flow rate to your house or not. b) Based on your evaluation, IF the pump is not sufficient to draw 70 Ls, propose a solution to solve...
2-32 You are reevaluating the industrial heat pump choice that was made last year by your boss. The expected energy savings have not occurred because the pump is too small. Choice A, at $90,000, is to replace the pump with one that is the right size and sell the old one. Choice B, at $100,000, is to buy a small pump to use in tandem with the existing pump. The two-pump solution has slightly higher maintenance costs, but it is...
Anyone can help me with this question?
2 - Heat pump .The heat pump illustrated beside uses 1.5 kw mechanical power (that's is 1500 J/s) and extracts 1.2 million calories per hour from the outside air . A) How much heat is pumped into the house every day? .B) If this heat pump is made such that it is ideal and reversible, and you decide to heat your house with a gas furnace and use the heat pump as an...
Outline how you would determine the amount of head needed to pump water from a low point to a higher point. Equations and diagrams might be useful.
A water tower is fed from an underground water source (Figure 2). The difference in level is 67 m. The flow of water must be at least 55 m'/h. To provide this flow (55m/h), a pump must be driven at a speed of 690 RPM. It can turn faster, but without exceeding 900 RPM. Its efficiency is 81%. The pump is driven directly, therefore without gearbox, by an asynchronous motor, which itselif is supplied directly by the 400V/50 Hz three-phase...
30 points You need to pump water at 20 °c from an open reservoir at flow rate of 14 x 10-3 m?s through a pipe with an inside diameter of 0.03 m, using a centrifugal pump having an (NPSH)req = 2.5 m and the equivalent length on the suction side is 3 m. There are several minor losses: four standard 900 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the entrance. What is the...
Here is the answer you should get for this problem
pump head = 330 feet, d = 0.78 feet so use 10” pipe
9. A farmer has a pump that is rated at 100 horsepower that he would like to utilize to irrigate potatoes. He needs to install 2500 feet of PVC pipe to extend from his pond at elevation 100 feet to his field at an elevation of 300 feet. He needs to supply 2 cfs with 50 psi...
