The blue line represents the point when the downstream Mach number becomes sonic. The chart assumes γ {\displaystyle \gamma } =1.4, which is valid for an ideal diatomic gas. For a given Mach number , M 1 , and corner angle, θ, the oblique shock angle, β, and the downstream Mach number, M 2 , can be calculated.
In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number, the post-shock Mach number can be calculated along with the pressure, density, temperature, and stagnation pressure ratios.

Across the expansion fan, the flow accelerates (velocity increases) and the Mach number increases, while the static pressure, temperature and density decrease. Since the process is isentropic, the stagnation properties (e.g. the total pressure and total temperature) remain constant across the fan.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
T is the absolute temperature B is the second virial coefficient. This relationship with osmotic pressure is one way to determine the theta condition or theta temperature for a solvent. The change in the chemical potential when the two are mixed has two terms: ideal and excess:
The thermodynamic beta was originally introduced in 1971 (as Kältefunktion "coldness function") by Ingo Müller , one of the proponents of the rational thermodynamics school of thought, [5] [6] based on earlier proposals for a "reciprocal temperature" function.
where is the Prandtl–Meyer function, is the Mach number of the flow and is the ratio of the specific heat capacities. By convention, the constant of integration is selected such that ν ( 1 ) = 0. {\displaystyle \nu (1)=0.\,}
