Total discharge head equation
WebCalculate the total head of a centrifugal pump and use the Darcy equation in computing the friction head in suction and discharge line. Consider the following data: water … WebNote that now that we’ve defined total head, we can translate these useful relationships into equations: H t = H d – H s. Where H t is the total head, H d is the discharge head and H s is the suction head. Also be aware that this equation holds true whether the suction head is positive (level of liquid in the suction tank is above the pump) or negative (level of the …
