I have a 1 HP water pump that will pump water through a 1 and 1/2hose. What is the approx. GPM (just to have a reference) of a pump like this?
The capacity will be limited by the pressure drop. Assume 15-40 GPM depending on the length of the 1 hose. This is provided that the 1 is then split into four 1/2 hoses. Otherwise the flow will be highly restricted by the smaller diameter. The efficiency of a small centrifugal pump is around 50%. The general water pump equation at 50% eff. is HP = GPM psi / 860. So for one horsepower the GPM = 860 / psi Therefore for 20 psi the flow is 43 GPM, at 40 psi it is 21 GPM , at 60 psi it is 15 GPM

many times the water pumps are AC grant pumps. in AC grant, you could not exchange the enter voltage and hence the area of utilising a million hp pump as 0.5 hp does not upward push up. ofcouse you could utilise 0.5 of its potential to pump water however the relax 0.5 would be wasted as warmth capability or frictional loss. the element is a a million hp pump will consume a similar potential what ever potential u choose to apply it.
It varies quite a bit but I would say anywhere from 6gpm - 10gpm.
Assuming the pump will produce about 50 psi of pressure and has an effiicienty of about 80% then the pump would pump about 25 to 30 gpm. I am assuming this is a centrifugal pump and if that is the case there are several varialbles that enter into the estimate. Take a look at the link below and you will see this is not a simple question to answer with any accuracy.
