Reynolds Number: Air at 1 m/s Over a 1 m Wing Chord
Airflow at 1 m/s over a 1-meter wing chord (standard air properties) produces a Reynolds number of about 67700, typical of low-speed aerodynamics.

Frequently asked questions
- What fluid properties should I use for water and air?
- Water at 20°C: ρ = 998 kg/m³, μ = 0.001002 Pa·s. Air at 20°C: ρ = 1.204 kg/m³, μ = 1.81×10⁻⁵ Pa·s.
- What is the characteristic length for a pipe?
- For flow inside a pipe, use the internal diameter as the characteristic length. For flow over a flat plate, use the plate length.
