What “tdh” means
WikipediaIn 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. TDH is essential for pump specification.TDH = Static Lift + Pressure Head + Velocity Head + Friction Loss
