WebDetermining pump power. After the system head has been calculated, it can be used to calculate an approximate pump power rating for a centrifugal pump: where P is the pump power (kW), Q is the flowrate (m 3 /hr), H is the total pump head (m of fluid), and η is the pump efficiency (if you do not know the efficiency, use η = 0.7). Webspeed of the pump, the higher the NPSH value will be. The NPSH value is measured on a pump test stand and cannot be modified without sup-plementary means. The NPSH value of the plant depends on the loss of head including the losses in fittings and apparatus in the line of the plant, and should be always checked by calculation. p E

If the Dynamic Discharge Head is 130 and the friction loss on the suction side is 10 ft, what is the vertical distance between the water level on the suction side and the centerline of the pump? Recall that for static suction lift, the pump is doing all the work.
