# Aerodynamic Reynolds number
# Scope: Characteristic Reynolds number at constant air properties.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

density = 1.225 kg/m^3
speed = 15 m/s
chord = 0.2 m
viscosity = 0.0000181 Pa*s

reynolds := density*speed*chord/viscosity

check model range example: reynolds >= 100000

scenario alternative: density = 0.98 kg/m^3
