Compressor Power Equation

The compressor power equation is used to calculate the power required to drive a compressor, considering factors like the pressure ratio, volumetric flow rate, and compressor efficiency. The most commonly used equation is:

$latex P = \frac{\dot{V} \cdot (P_2 – P_1)}{\eta} $

Where:

• $P$ is the power required (in watts),
• V˙\dot{V}V˙ is the volumetric flow rate (in cubic meters per second),
• P1P_1P1​ and P2P_2P2​ are the inlet and outlet pressures (in Pascals),
• $\eta$ is the efficiency of the compressor.

This equation helps in sizing compressors, optimizing energy consumption, and ensuring efficient operation in various industrial applications.
