A diffuser receives air at 80 kPa and 100°C at a velocity of 150 m/s and a mass flow rate of 2.1 kg/s. The air exits the diffuser at 120 kPa and 135°C, at a velocity of 15 m/s. The surface of the diffuser is maintained at 25°C. Determine the entropy generation rate for the process. Is the process possible? If not, suggest some possible explanations.
