Enter the inlet temperature, outlet temperature, molar weight, throughput, and isentropic coefficient into the calculator to determine the compressor power.

Centrifugal Compressor Power Formula

The following equation is used to calculate the Centrifugal Compressor Power.

P = 2.31 * k/(k-1) * ((To-Ti)/M)*Q
  • Where P is the power (kW)
  • k is the isentropic gas coefficient.
  • To is the outlet temperature (C or K)
  • Ti is the inlet temperature (C or K)
  • M is the molar weight of the gas (g/mol)
  • Q is the throughput (t/h)

What is a Centrifugal Compressor Power?


Centrifugal Compressor Power is the power required to run a centrifugal compressor. The term can also be applied to the power produced by the compressor.

Centrifugal Compressor Capacity is the flow rate at which an air conditioning refrigeration unit can handle. This is determined by the amount of heat that needs to be eliminated from an area.

Centrifugal Compressor Work is the mechanical energy needed for a centrifugal compressor to deliver refrigeration. It’s important to remember that work and capacity are not the same thing.

Work is generated by a motor, while capacity is how much heat an air conditioner can remove from an area (work and capacity are related, since work = force x distance).

What are centrifugal compressors?

Centrifugal compressors are a type of motorized compressor that use a rapidly spinning wheel to compress gases. These machines can be powered by electricity, gas, or steam. Centrifugal compressors are most commonly used in HVAC systems. They are often installed in residential and commercial buildings to provide heating and cooling.
