What is the relation between pressure and density in an adiabatic air flow?

A. \(\frac{p_1}{p_2}\)=(\(\frac{\rho_1}{\rho_2}\))\(\frac{1}{\gamma}\)
B. \(\frac{p_1}{p_2}\)=(\(\frac{\rho_1}{\rho_2}\))γ
C. \(\frac{p_1}{p_2}\)=(\(\frac{\rho_1}{\rho_2}\))γ+1
D. \(\frac{p_1}{p_2}\)=(\(\frac{\rho_1}{\rho_2}\))γ-1
Answer» C. \(\frac{p_1}{p_2}\)=(\(\frac{\rho_1}{\rho_2}\))γ+1
