WebAug 21, 2024 · Further, HI defines total dynamic head (TDH) as the measure of energy imparted to the liquid by the pump. More specifically, TDH is the difference between discharge head and suction head as measured between the inlet and outlet of the pump, including the energy required to overcome static elevation, friction and other losses. WebThe sum of the head and friction loss will give total head. Total head is a more reliable indicator of pump performance than pressure because it indicates what the pump can do regardless of the suction conditions. The total head combined with your flow requirement will allow you to choose the right pump. The performance of the pump at a certain ...
