Flow rate [m h] Total head [m] - Fristam

The flow rate is the effective volume flowing per unit of time through the discharge connection of a pump. In order to optimize the pump design, the flow rate must be accurately determined. The total head is the effective mechanical energy transferred by a pump to the fluid as a function of the weight force of the fluid.
