Centrifugal pump Affinity laws are set of mathematical equations correlating the Flow Rate, Head, Brake Horse Power, Speed and Impeller Diameter of the pump. Pump efficiency is considered as a constant and variation in speed and impeller diameter is analyzed for the variation in above said parameters. Using the new set of data derived from pump affinity laws a new set of pump … [Read more...]
Pump Specific Speed Calculation
Pump Specific speed is a dimensionless number used in design. Specific speed is used to find out the geometry of the impellers and it is helpful in identifying the type of impeller to be selected for particular application. Formula for Calculation of Pump Specific Speed Specific speed of the pump is calculated with the help of the formula: Ns = (N * √Q )/ … [Read more...]

Centrifugal Pump Efficiency Calculation
Centrifugal pump efficiency is the ratio of Hydraulic power delivered by the pump to the brake horsepower supplied to the pump. Hydraulic Power (Power Output from Pump): Centrifugal Pump consumes energy to develop the discharge pressure and to deliver flow. Therefore Hydraulic Horsepower of the Pump depends on these two parameters. Power Output from Pump = (P2 – P1) * … [Read more...]
