Horsepower Calculator

The following calculation method uses the Gas Processors Suppliers Association Engineering Data Book Eleventh Edition, FPS Version, 1998, eq 13-4 developed for large slow speed (300-450 RPM) compressors with SG = 0.65 and having CR > 2.50. Discharge temperature based on eq 13-18 assuming 130 Deg F inlet and k of 1.3
Brake Horsepower = 22 * (ratio/stage) * (Number of Stages) * ( MMSCFD) * (F) where F = 1.0 for a single stage, 1.08 for a two-stage and 1.1 for a three-stage.

For example: it will require 299 horsepower of compression distributed among 3 stages to move from a suction pressure of “0” to a discharge pressure of “1000” for every 1000 MCFD.

For a flow of 500 MCFD, 50% (500 MCFD/ 1000 MCFD) of the horsepower is required.
