Total Dynamic Head

"Head" is a word engineers use for pressure. This calculator determines the pressure (head) required just after the pump, and the pressure (head) that the pump must generate or add. The required pressure just after the pump (total dynamic head) includes pre-existing pressure of water entering the pump, pressure needed to overcome elevation differences (sometimes pressure is added if flowing downhill), and the pressure losses due to friction in the pipes in order to produce the required pressure at the emitters, or sprinklers.    Determine the pressure (head) required just after the pump, and the pressure (head) that the pump must generate or add. (Based on water properties)
Elevation Change (positive = pumping upward, negative = pumping downward):	ft m
Pressure Required in the System:	ft of water m of water bars milli bars kPa atm in of Mercury psi
Friction Head Loss in the Pipeline:	ft of water m of water bars milli bars kPa atm in of Mercury psi
Inlet Pressure at the Pump:	ft of water m of water bars kPa atm in of Mercury psi
Total Dynamic Head (Pressure) Needed:	ft of water m of water bars kPa atm in of Mercury psi
Total Dynamic Head (Pressure) the Pump Must Generate (Use this to specify your pump.):	ft of water m of water bars kPa atm in of Mercury psi
