Q:What does the lift of a pump mean?: Simply from the local to the pumping pumping height calculation of rice

Q:I know that the water pump is belt driven, so it would be easy to connect it to my bicycle. What I am wondering is if I can pedal fast enough to make it work. Does anyone know how fast I would need to pedal to operate the pump?: Pretty fast. Engines operate at 600-6000 rpm and the pump pulley is a little smaller than the drive pulley, so it is spinning even faster. That said, 600 rpm is plenty fast enough. You can attain that easily by applying pulley to rear tire tread, raising tire off ground and pedaling. To apply bike chain to pulley would give a disappointing water flow.

Q:A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 for pi . Round your answer to three significant digits.)The tank is a spherical shape has a radius r= 6m and a spout height of h=2m.I really dont know how to start this problem correctly. Any help will be appreciated. Thanks!: The pump will not have to work until the water drains by gravity to the level of the spout. Then, Work = Weight of water * Height of lift Find the distance, d, of the center of mass for the remaining water in the bottom 2 m of the sphere. The height of lift will then be 2m - d. The hardest part is finding the distance d to the center of mass. I don't remember how to do that.

Q:Under what circumstances should we set up fire pool and fire pump room? Is it necessary to have a building?: These facilities are available only in large public buildings.

Q:I'm curious to know, where does the water go after it is sent to a pumping station??: Potable (drinkable) water pumps placed just outside the treatment plant boost pressure in the water mains, where it eventually gets to homes, businesses and hydrants via the pipe network. Most sewers flow by gravity (downhill) to a waste water treatment plant (or septic field). But if an area is too low to be serviced by a gravity sewer, an ejector pump is set at the bottom of a collection well which pumps the wastewater to a higher elevation in a pressure pipe called a force main. A good pump station will kick on about 4 or 5 times an hour and run for several minutes. Eventually it outlets to a manhole in a gravity system and ultimately the treatment plant.

Q:Pump head is too high what's the impact?: Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.

Q:How to determine the pump installation elevation, why should we determine the pump installation elevation?: Water pump installation elevation should be in accordance with the water pump suction head, taking into account the water level of water intake and fall. The minimum water level at the water intake point must be less than the suction head of the water pump, otherwise the water intake will not be enough.

Q:I keep having to add water to. Doesn't do anything when it's sitting up. But after you drive it straight for about 25 minutes. Time to add some more water. I figure it's the water pump. It's not leaking anywhere so it has to be a failing water pump. Oil still looks good, no smoking. AC and heater blows fine. Just runs hot after a while. I need another opinion. Its the 4 cylinder also. And yes it does be steaming. Tired of having to add water everyday.: Forget the check this and try that stuff. You need a RADIATOR SHOP the radiator is plugged and you can do nothing to clean it. Don't waste time on flushing as it is a waste. Water pumps have mechanical seals and require no lubrication and anti freeze contains no lubrication material. Plain water will not affect the pump. Never replace any part 'till you KNOW the problem

Q:I have a Goulds JPlus water pump inside my home. Last night, my wife and I heard it going on and off repeatedly when we went to bed. I have two shallow wells hooked up to it, so I switched wells even though I didn't believe the one I was on was dry (it was supplying H2O fine).Still no luck, so I turned it off at the breaker and shut off the valve between the tank and pressure switch. Today, the pump pressure gets to between 50 and 60, then goes off. It then loses pressure v ery quickly (approx 10-20 seconds) and goes back on when the pump switch hits the lower threshold. It sounds like the water is running back through the pump and out of the house when it goes off unless I turn the shut off valve I spoke of earlier. I changed the pressure switch and no difference.I can, however, turn it on and shower, flush, etc. I just then have to go down and turn the pump back off.Any help would be greatly appreciated!: Do you have an air tank hooked to the pump? That is what usually holds pressure while the pump is off. It may have a leak in the bladder.
