WebFor example, if we have a motor with 3,000 rpm and 6 in-lbf then the horsepower can be calculated below. Horsepower =. i.e. horsepower = 0.286. Here, 63025 is a constant when using rpm for speed and in-lbf for torque units. 5252 is another common constant if the speed is in rpm and torque is in ft-lbf. Web———————————– = Theoretical horsepower. 3960. For example: 39.6 gpm X 100 ft of head ... The theoretical horsepower formulae above is shown, because many of the water permits will require stream potential in t hp. Hydro power potential, flow charts, and pipe loss are figured on a standard water temperature of 68.4 F which ...

WebHorsepower = 3960 x Pump Efficiency: CAPACITY is the rate of flow, in gallons per minute. COLUMN FRICTION LOSS is the friction loss, in feet of head, through the column and is dependent upon both capacity and the length and diameter of column and shaft used. Column friction loss is indicated in feet of heat per hundred feet of column and shaft. Web3960 Horsepower (hp) = 2912575.248 Joule/Second (J/s) Visit 3960 Joule/Second to Horsepower Conversion.
