Air enters a diffuser in order to decrease its pressure from 65 kPa to 45 kPa. At the inlet, its temperature is 25°C with a velocity of 200 m/s and a mass flowrate of 3 kg/s. During the process, the air loses heat at 24 kW. Given that H1 = 309.56 kJ/kg and H2 = 320.54 kJ/kg, what is the velocity of air in m/s as it leaves the diffuser?
