Piston Compressor Displacement & Flow Calculator
Calculates ideal geometric displacement from bore, stroke, cylinder count, and rpm. Applies single/double-acting selection and volumetric efficiency to estimate efficiency-adjusted displacement flow. Results are not Free Air Delivery (FAD).
Inputs
Results
Geometric displacement (cc/rev)254.5 cc
Geometric displacement (L/rev)0.254 L/rev
Geometric displacement flow356.3 L/min
Efficiency-adjusted displacement flow285.0 L/min
Model boundary: This result is ideal geometric piston displacement, not FAD. Double-acting mode assumes full bore area on both faces; rod area, clearance volume, valve/leakage losses, pressure ratio, and FAD reference conditions are not modeled.
