In a liquid-oxygen plant, it is proposed that the pressure and temperature of air that is initially at 9000 kPa and 10°C be adiabatically reduced to 50 kPa and −73°C. Using Kay’s rule and the departure charts, determine whether this is possible. If so, then how much work per unit mass will this process produce?
