# Cylinder speed and flow
# Scope: Incompressible flow/piston area speed; pneumatic flow must use cylinder conditions.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

flow = 5 L/min
diameter = 32 mm

area := pi*diameter^2/4 [mm^2]
speed := flow/area [mm/s]

check speed budget: speed <= 150 mm/s

scenario alternative: flow = 4 L/min
