WebDec 5, 2024 · Horsepower, or HP, is the amount of power required for a pump or turbine to transfer a fluid or to create a flow in the fluid. This depends on the rate the fluid is lifted and the height to which it is lifted. The rate is usually measured in gpm, which stands for gallons per minute, and the height is usually measured in feet. WebAmperage can be found on your pump’s motor spec sticker and usually indicated by “Amps” “SFA” or simply “A”. Single voltage dual speed pumps will show 2 amperage ratings for example, 12.0/3.5. The larger representing high speed and the smaller will represent the low speed. Dual Voltage (115v & 230v) will also show 2 amperage ratings.
WebThe efficiency of any given pump (η) is a ratio defined as the water horsepower out divided by the mechanical horsepower into the pump. η = water hp out / hp into pump 0 < η < 1. If the pump in the last example uses 17.0 HP to provide 13.0 WHP, the pump efficiency is: η = 13 / 17 = 0.76 or 76% http://www.royalhydraulics.com/newrsg/support/13-support/29-fluid-power-formulas
WebPump system calculations, metric units. Power is given by the combination of four items: the specific gravity SG, the total head , the flow rate Q and the efficiency of the pump eta .The specific gravity SG is the ratio of the fluid's density to that of water at standard conditions, for water the value of SG equals 1. WebSep 14, 2024 · Specific Gravity Pressure Calculation: The pressure supplied by a pump for each application is fluid dependent and relative to fluid density thus pressure will change according to the fluid’s specific gravity. To obtain the pressure in Bar - multiply 0.0981 by the Head in Metres displayed at duty point, by the Specific Gravity of the Fluid.
