Pump Input Power = P Formula – 1 Here Q = Flow rate in m3/sec H = Total developed head in meters ρ= Density in kg/m3 g = Gravitational constant = 9.81 m/sec2 η = Efficiency of the pump ( between 0% to 100%) Formula – 2 ...
(2) P Nominal displacement of q= pump (ml/reV) N= speed (RPM) Volume v = pump efficiency (general 0.90-0.95) F= frequency (50/60HZ) P= pole number (2, 4, 6 poles) (gear pump formula) input power (pump) calculation formula: when a certain pressure P, the input power changes ...
4.4.4 Measurement of power input (P) The power input of the pump is determined either electrically by means of a calibrated test motor or by directly measuring the speed of rotation using a torque measuring hub. The electrical measurement is made according to the two-watt meter method for de...
A Pump Power Calculator is a software application designed to calculate the power required for a pumping system. It takes into account various factors such as the liquid being pumped, the size of the pump, the height of the delivery pipe, and the flow rate. The user inputs the necessary ...

1)How to convert HP into KW ? The conversion formula as :1HP=0.74KW for example: 3PH=3x0.74KW/PH=2.22KW. 2)How to choose the power of your pump controller? Normally we need choose bigger power to run the water pump or motors,.If the pump rated power is 4KW,Pump controll...
We have found that within the angular range used for scanning, the combination of beam expander and objective linearly transforms the angular deviation of the input laser beam into a lateral translation of the focal point position at the object plane. Because the field aperture plane is ...
