# Answer to Question #79126 in Mechanical Engineering for Emmanuel Peter

Question #79126

0.5kg of air is compressed reversibly and adiabatically from 80kpa, 60°c to 0.4Mpa and is then expanded at constant pressure to the original volume. Calculate the heat transfer and work transfer for the whole path.

Take R = 0.247kj/kg.k, Cp = 1.005kj/kg.k, Cv = 0.718kj/kg.k

Take R = 0.247kj/kg.k, Cp = 1.005kj/kg.k, Cv = 0.718kj/kg.k
