Q:sump pump, no water.?
yes the ground water in your area is draining back into the ground away from you which is what you want
If you just installed it you may have hooked it up backwards. The intake and output may be reversed or your electrical connection my be opposite what it is supposed to be. Take of the output side and put your finger over it. It should be creating pressure and blow on your finger. If that is not the problem check to see if you have a water filter between the tank and the pump. That my be clogged.
Q:I have a small drip coming from the raw water pump, whats the problem?
Usual answer is to look for the flats of the gland on the shaft on tighten up with a spanner,as this will compress the packing a bit more. A small drip is not very bad but you are right to check.
Q:How can I test how high a water pump can pump to, using only pressure simulation?
*you can go by the 1st answer as pressure gauge near the pump discharge would give a maximum pressure inclusive of losses. As the losses are more[due to piping congetion or rasistance from the equipment to which it is pumping.] then the discharge head will be decreased. *Simply, in case of a centrifugal pump,close the discharge valve fully for a moment and check the discharge pressure. This is the maximum pressure ,your pump will pump. *Dont do this if the pump is positive displacement pump/regenerative turbine pump. Edit: Discharge head means pumping height in your case.
Q:Work done in water pumping?
Power_W = (Mass_kg * Gravity_m/s/s * Height_m) / time_s Where: Mass kg is 1kg/l of 2000 liters Gravity is 9.81m/s/s Head is 60m + 10m (height). The suction head is ignored because the pump is submerged. In practice there is some suction head due to intake restrictions like pipes, check valves, strainers. The time is 20 minutes in seconds. The work is the energy used in the time allocated, which is: power * time in seconds, which is watt seconds = joules. Not needed here as it is in the formula above. Power is the rate of doing work. The depth below water is not really relevant except for pipe losses which increase the head slightly. The flow is 2000 liters/20 minutes = 100 l/min. This can be used with the head of 70m to determine the pipe restriction, which amounts to a pressure drop representing extra head added. It will indicate whether the pipe is too small (excessive head added) or whether the pipe is overkill (no head added). You can find on line calculators for this, e.g. search pipe resistance flow on line calculator. I am guessing a 2 inch pipe has little loss at this flow. This is the so called water power. It is the output power of the pump. The pump may only be 50% or so efficient, so the mechanical power delivered by the motor needs to be greater by this ratio. The electrical input power to the motor is greater again to allow for motor efficiency. This might be 60-90%. In practice the efficiency of pump and motor are determined from user manual or specification of the actual devices with the actual loads (head and flow).
Q:How much 4 water pump,spark plug replacement for 1998 BMW328i 90kserivce?
You will be lucky if you pay only $500. Plan on a GRAND...
Q:laundry washer water pump?
Sounds like the pump is operating during the fill cycle. if there is something clogging the pump, you wouldn't be losing water, it would never drain.
Q:Timing belt and water pump change?
There is no guarantee on how long the water pump will last, but normally 100,000 miles plus. But that is true of a timing belt too. The water pump has a weep hole at the bottom, visually check for corrosion or rust in that area. If you see some, could be a sign that it is ready to go soon. If not, then do the repairs that you can afford. But why the heck are you changing a timing belt at 60,000 miles.
Q:Power flow conversion of water pump
Pump shaft power (kw) = water supply (L / s) x lift (m) /102 * efficiency = flow * lift * density * acceleration of gravity.Explanation:102 is the unit collation constant.Pump effective power / pump shaft power = pump efficiency (general 50%--90%, large pump higher)Unit time pump liquid volume flow is, flow by Q, a unit of measure: m3 / h (m3/h), L / S (l/s), L/s=3.6 m3/h=0.06 m3/min=60L/minG=Q G refers to weight - liquid proportionThe energy obtained by pumping a liquid of a unit weight is called a lift. The pump head, including suction stroke, is approximately the difference between the pump outlet and inlet pressure. The lift is expressed in H, and the unit is m.The efficiency of a pump is the ratio of the effective power to the axial power of the pump. ETA =Pe/P pump power usually refers to the input power, the motive power to the pump shaft, it is also called the shaft power, denoted by P. Effective power is the product of pump head and mass flow and gravity acceleration
Q:Replace the water pump on a 1992 Pontiac Sunbird LE?
The best thing you could do is maybe run to a library and they might have a Chiltons or Haynes repair manual you can make some copies of, check it out and decide for yourself, but a timing belt is a pretty involved process, not so much for a water pump.
