Problem 2.33

Calculate the value of $\gamma=C_{p} / C_{V}$ for a gaseous mixture consisting of $v_{1}=2.0$ moles of oxygen and $v_{2}=3.0$ moles of carbon dioxide. The gases are assumed to be ideal.

Reveal Answer

\gamma=\frac{v_{1} \gamma_{1}\left(\gamma_{2}-1\right)+v_{2} \gamma_{2}\left(\gamma_{1}-1\right)}{v_{1}\left(\gamma_{2}-1\right)+v_{2}\left(\gamma_{1}-1\right)}=1.33
