Manometric head in pump

Web01. apr 2024. · The profile of the electrical load of the wastewater pumping station E L (t) depends on the hourly flow rate of the pump Q(t), the total manometric head (H), the hydraulic constant C (C = density of water × gravity constant), and the efficiency of the moto-pump group η M-P, it can be calculated using Eq. 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 ...
