Consider that a flow of air with a velocity of 270 m's enters an adiabatic diffuser at a pressure of 60 kPa and a temperature of 7°C and exits the diffuser at a pressure of 85 kPa and a temperature of 27°C. Use variable specific heat approach to indicate the air properties. Calculate the ratio of the inlet area to the exit area of the nozzle.
