Sound Speed of Ideal Gases
Assumptions: Isentropic flow of an ideal gas with constant specific heats
\( \displaystyle
c = \sqrt{kRT},
R = \frac{\bar{R}}{M}
\)
Symbols
- \(c\) — sound speed
- \( k \) — specific heat ratio, Cp/Cv
- \( R \) — gas constant
- \( \bar{R} \) — universal gas constant (8314 J/(kg·K))
- \( M \) — molar mass
- \( T \) — thermodynamic temperature
