# Pneumatic air consumption
# Scope: Isothermal free-air equivalent per double-acting cycle; rod volume omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

diameter = 32 mm
stroke = 100 mm
absolutePressure = 700 kPa
referencePressure = 100 kPa
cycles = 10 min^-1

swept := pi*diameter^2*stroke/4 [L]
referenceFlow := 2*swept*absolutePressure/referencePressure*cycles [L/min]

check free air budget: referenceFlow <= 15 L/min

scenario alternative: diameter = 25.6 mm
