6 62 WP Air at 200 kPa 52 C and a velocity of 355 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
