Screw Compressors- Mathematical Modelling And Performance Calculation Jun 2026

Polytropic work per unit mass: w = (R T1 /(1 − n)) [(p2/p1)^(1−n)/n − 1] (derived from integrated p dV with pV^n const) If n = 1 (isothermal): w = R T1 ln(p2/p1)

If you design, select, or maintain these machines, understanding we model them mathematically is the key to predicting real-world performance —not just brochure specs. Polytropic work per unit mass: w = (R
