An ideal gas, initially at 29 and 105 kPa, with Cp, = 7R/2 and Cv, = 5R/2 undergoes the following cyclical process in a closed system. In a mechanically reversible process, there is first an adiabatic compression to 600 kPa, then a constant pressure cooling of 600 kPa to 29 , and finally an isothermal expansion to its original state. (a) Sketch the PV diagram the process path for this cycle. (3) (b) Calculate the w, q, U and H (in J) for each of the process. (5+5+5+5) = (20) (c)Calculate the overall w, q, U and H (in J) for the cycle.
