Air at 480Kpa is expanded adiabatically to a pressure of 94Kpa.It is then heated at constant volume until it again attains itstemperature, when the pressure is found to be 150KPa. it thenundergoes an isothermal compression to return the air to itsoriginal state. Using this information sketch the p-v diagram andcalculate the value of γ. If the initial temperature of air is190oC determine the work done per kg during theadiabatic expansion and teh isotherman compression. Calculate thechange in enthropy during the constant volume process.
Take R= 0.29KJ/KgK
