pub fn critical_reynolds(relative_roughness: f64) -> Result<f64, AeroError>Expand description
The roughness-limited critical Reynolds number R_crit = 51 (R_s/L)^−1.039 (Niskanen 2009
eq. 3.79; Barrowman 1967 eq. 4-7), infinite for a perfectly smooth surface.
§Errors
AeroError::Domain for a negative or non-finite relative roughness.
