Isentropic stagnation pressure
Calculates stagnation pressure for an isentropic ideal-gas model.
Mach number
Calculates Mach number as the ratio of flow velocity to speed of sound.
Speed of sound in ideal gas
Calculates speed of sound from heat capacity ratio, specific gas constant, and temperature.
Stagnation temperature
Calculates stagnation temperature for an isentropic ideal-gas model.
Simple compressor power
Calculates auxiliary compressor power from pressure increase, flow, and efficiency; it is not device selection.
Simple receiver tank pressure decay
Calculates auxiliary receiver pressure decay; this is a diagnostic simplification, not an exact thermodynamic model.
