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...]

Minimum Thermal Flow in Centrifugal Pumps
What is Minimum Thermal Flow in Centrifugal Pumps? Minimum Thermal Flow in Centrifugal Pump is defined as, “The lowest flow at which the pump can operate without its operation being impaired by the temperature rise o f the pumped liquid” The temperature of the liquid in the pump casing is to be kept below the saturation temperature of the liquid. The overheating of the …[Read more...]
