Question: Consider a jet engine operating on the Brayton cycle. The working substance is air, which consists primarily of diatomic molecules. The air is drawn in

Consider a jet engine operating on the Brayton cycle. The working substance is air, which consists primarily of diatomic molecules. The air is drawn in at atmospheric pressure, $1.01 \times 10^{5} \mathrm{~Pa}$, at $288 \mathrm{~K}$. In the combustion chamber, the temperature of the air is raised to $1520 \mathrm{~K}$, and the engine has a pressure ratio of 30 . What are the temperatures at the end of the two isentropic processes?
