Air enters an adiabatic compressor at 300K. The exit temperature for a compression ratio of 3, assuming air to be an ideal gas (Y = Cp/Cv = 7/5) and the process to be reversible, is___________________?
Correct answer: A
Explanation
For an adiabatic process with an ideal gas, the exit temperature T2 is found using T2/T1 = (r_p)^k / (r_p - 1), where k=Y. Here, T2 = 300 * (3^7 / (3^5 - 1)).
