An ideal gas undergoes two processes in a piston cylinder device, from 1-2 a polvtropic compression from T1 and P1 with a polvtropic exponent n and a compression ratio of r = V1/V2 where V1 and V2 are the initial and the final volumes. From 2-3 the process is a constant pressure expansion at P3 = P2 until V3 =V1. Sketch the entire process P-V diagram, Obtain an expression for the ratio of the compression-to-expansion work as a function of n and r and Find the value of this ratio for values of n = 1.4 and r = 6.
