pub fn newtonian_surface_mach(
mach: f64,
pressure_ratio: f64,
) -> Result<f64, AeroError>Expand description
The cap’s surface Mach number where its pressure is pressure_ratio times the free stream’s,
isentropic from the pitot pressure (TN D-4865 eq. 2); zero at the stagnation point. The
report’s march starts from it (crate::shock_expansion::HandoverStart::Newtonian).
§Errors
AeroError::Domain for a Mach number that isn’t finite and above 1, or a pressure that
isn’t positive and at most the pitot pressure.
