Extracted text: Air at 200 kPa, 52°C, and a velocity of 305 m/s enters an insulated duct of varying cross-sectional area. The air exits at 100 kPa, 82°C. At the inlet, the cross-sectional area is 6.57 cm?. Assuming the ideal gas model for the air, determine: (a) the exit velocity, in m/s. (b) the rate of entropy production within the duct, in kW/K.
