Answer to Question #312761 in Mechanical Engineering for San

Question

In a piston-cylinder arrangement of an engine there are 0.1 kg of gases at 4 MPa and 1527 °C at the beginning of the expansion stroke. The gases expand in a polytropic process with n =1.5 to a volume 10 times larger. Find the expansion work and the heat transfer. Assume the gas to be perfect gas with R= 0.287 kJ/kg-K, and Cv= 0.717 kJ/kg-K.
