# Centrifugal Pump Minimum Flow Rate Calculator

A sub-class of dynamic axisymmetric work-absorbing turbomachinery are Centrifugal pumps. Generally used for water, sewage, petroleum and petrochemical pumping. A centrifugal pump aids in transporting fluids by conversion of rotational energy, often from a motor, to energy in a moving fluid. Calcuate minimum rate of fluid flow in a centrifugal pump using this online Centrifugal Pump Minimum Flow Rate Calculator based on specific heat capacity, specific gravity of the fluid and power input.

## Calculate Minimum Flow Rate of Centrifugal Pump

A sub-class of dynamic axisymmetric work-absorbing turbomachinery are Centrifugal pumps. Generally used for water, sewage, petroleum and petrochemical pumping. A centrifugal pump aids in transporting fluids by conversion of rotational energy, often from a motor, to energy in a moving fluid. Calcuate minimum rate of fluid flow in a centrifugal pump using this online Centrifugal Pump Minimum Flow Rate Calculator based on specific heat capacity, specific gravity of the fluid and power input.

#### Formula:

q = (PBHP / 2.95) x cp x SG Where, q = Centrifugal Pump Minimum Flow Rate PBHP = Power Input cp = Specific Heat Capacity SG = Specific Gravity of the Fluid

### Example:

If the power input is 25 BHP, specific heat capacity is 33 Btu/lb °F and specific gravity of fluid is 10 kg/m3

#### Solution,

q = (PBHP / 2.95) x cp x SG
= (25 / 2.95) x 33 x 10
= 2796.61 gpm
