Water Pump Head Calculator

Pump sizing calculation this tool does hydraulic calculation for a pump and estimates differential head hydraulic power motor power npsh available.

Water pump head calculator. Water drawdown level is defined as the lowest water level in the well after long time pumping. Enter total pumping lift or height feet water is pumped vertically. Water pump calculator calculate pressure head total dynamic head bowl horsepower total trust acting on driver thrust bearing field head power loss due to shafting power loss in thrust bearings motor load field efficiency input horsepower power supplied to driver and shaft elongation. From water drawdown level to highest point in the pipe set up.

1 m3 h of water is pumped a head of 10 m. Convert from pressure pounds per square inch psi to head of water in feet ft h2o convert from pressure bar to head of water in meter m h2o. Head loss filters heater chiller skimmer uv etc. If you have to pump water to the fifth floor of an apartment building and want to have 45 psi water pressure available to the occupants you can determine the minimum pump pressure required at ground level.

Water horsepower is the energy or power added to water by the pump. 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 0 027 kw. Head calculator use the form below to calculate the total dynamic head tdh of your pumping system. Calculate the hp flow rate or discharge and total head using this simple online calculator.

Total dynamic head tdh calculator. Pump head calculation uses bernoullis principle which states that the total energy at a given point in a fluid depends upon the energy of movement of the fluid plus energy from static pressure in the fluid plus energy from the height of the fluid relative to a specific data.
