2.2 Ideal Gas

Gas that obey the equation of state $ P = \rho R T$, the speed of sound is

$\displaystyle c = \sqrt{ k R T}$ (2)

Gas that obey the equation of state $ P = z \rho R T$, the speed of sound is

$\displaystyle c = \sqrt{nz R T}$ (3)

Where $ n$ is defined as

$\displaystyle n = \overbrace{C_p \over C_v}^{k} \left( z + T \left( \partial z ...
...ight)_{\rho} \over z + T \left( \partial z \over \partial T \right)_{P} \right)$ (4)
