The specific speed of a centrifugal pump is defined as the speed of an imaginary pump, identical with the given pump, which will discharge 1 liter of water, while it is being raised through a head of one meter. Mathematically, specific speed,
The ranges of specific speeds for different types of pumps are given in the following table.
