It is assumed that the gas can be considered to be an ideal gas and that the calorically perfect gas assumption applies.
With the assumptions above, speed of sound is a function of temperature and gas properties
Specific heat at constant pressure, \(C_p\), and specific heat at constant temperature, \(C_v\), are calculated from the specified gas data according to:
The sonic conditions (starred quantities) are the flow conditions that we would get if we could slow down or accelerate the fluid to sonic speed adiabatically (without adding or removing heat). If the sonic conditions are normalized suing the corresponding total/stagnation properties (the flow conditions we would get if we could slow the fluid down to zero velocity isentropically), it becomes a constant for a specific gas.
