Point 2: x 2 = 0, y 2 = Shut-Off Head (SOH) The shut-off head is calculated using the formula: SOH=RPH (1+θ) Where θ = Head Rise to Shut-off Ratio. A 0.25 to 0.30 head rise to shut-off ratio is a reasonable value for centrifugal pump calculations. Usually, the lower the value the flatter the curve. A head rise to shut-off ratio of zero .
Centrifugal pumps are widely used in various industries for fluid transportation. Understanding the discharge equation of a centrifugal pump is crucial for optimizing its performance and efficiency. The discharge equation of a centrifugal pump is derived from fundamental principles and laws governing the operation of these pumps.
If the discharge of a centrifugal pump is pointed straight up into the air the fluid will pumped to a certain height - or head - called the shut off head. This maximum head is mainly determined by the outside diameter of the pump's impeller and the speed of the rotating shaft.
