WebIn fluid dynamics, total dynamic head ( TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid. TDH is expressed as the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe. Static lift is the difference in elevation between the suction point and the discharge point. WebThe total head is equal to the difference between the pressure head at the discharge H D and the pressure head at the suction H S. H S is equal to –15 feet because it is a lift therefore: H D = 100 + (-15) = 85 feet. The discharge pressure will be: Now you can check your pump to see if the measured discharge pressure matches the prediction.
