Engineering Reference
Compression Ratio (CR)
CR = (P_gauge + P_atm) / P_atm
Free Air Volume
V = Area × Stroke × CR
- P_atm ≈ 1.013 bar (Standard atm pressure)
- CR = Absolute pressure ratio
- Double Acting = Consumes air on both strokes
- L/min (ANR) = Normal liters of free air delivery
- SCFM = Standard cubic feet per minute
