Horsepower Required to Compress Air Table Chart

Horsepower required to compress one cubic foot of free air per minute (isothermally and adiabatically) from atmospheric pressure (14.7 pounds per square inch) to various gage pressures. Single-Stage Compression, initial temperature of air, 60°F, jacket cooling not considered.

Adiabatically
Adiabatically

The equation for calculating the horsepower required to compress isothermally a given volume of free air to a given pressure:

Isothermally
Isothermally

Where:

HP = Horsepower (ft-lb/sec) Adiabatic and Isothermally
N = number of stages in which compression is accomplished
P = atmospheric pressure in pounds per square inch
P2 = absolute terminal pressure in pounds per square inch
P2 = Gp + P in pounds per square inch
Gp = Gauge Pressure in pounds per square inch
V = volume of air, in cubic feet, compressed per minute, at atmospheric pressure
n = exponent of the compression curve = 1.41 for adiabatic compression
