WebFeb 17, 2009 · Power needed by the fluid. Pump_hydraulicHP = Q_cfs * 62.4 * SG * PumpDiffHead_ft / 550 Power needed by the pump. PumpBHP = pump_hydraulic_HP / Pump_Efficiency Delivered Motor Power (often called motor shaft power) must be greater or equal to your maximum PumpBHP, plus a small safety margin of 10 to 15%, often … 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.

WebApr 26, 2013 · When the speed of an AC motor is controlled by a VFD, HP or torque will change depending on the change in frequency. Figure 1 provides a graphical illustration of these changes. The X axis is motor speed from … WebWhen a more viscous fluid is handled by a centrifugal pump. brake horsepower requirement increases; the head generated is reduced; capacity is reduced; efficiency of pump is reduced and the Best Efficiency Point - BEP - is moved; The head, flow and capacity with fluids with other viscosities than used in the original documentation can be modified with coefficients. oyster bay lcbo
Pump Design Equations Formulas Calculator Water Horsepower
The ideal hydraulic power to drive a pump depends on 1. the mass flow rate the 2. liquid density 3. the differential height - either it is the static lift from one height to an other or the total head losscomponent of the system - and can be calculated like The hydraulic Horse Power can be calculated as: Or - alternatively See more 1 m3/h of water is pumped a head of 10 m. The theoretical pump power can be calculated as Ph(kW) = (1 m3/h) (1000 kg/m3) (9.81 m/s2) (10 m) / (3.6 106) = 0.027kW See more The shaft power - the power required transferred from the motor to the shaft of the pump - depends on the efficiency of the pump and can be calculated as See more The calculator below can used to calculate the hydraulic and shaft power of a pump using Imperial units: 1. Check the relation between Density, Specific Weight … See more 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% WebApr 13, 2024 · Pump Input Horsepower - HP: HP = GPM × Pressure (psi) / 1714 × Efficiency: HP = (Q ×P) / 1714 × E: Pump Efficiency - E: Overall Efficiency = Output HP / Input HP: E Overall = HP Out / HP In X 100: Overall Efficiency = Volumetric Eff. × Mechanical Eff.
