Air flows in a 20-cm-diameter duct at 120-c and 120 kpa


Air flows in a 20-cm-diameter duct at 120-C and 120 kPa with a mass flux of 5 kg=s. The circular duct converts to a 20-cm square duct in which the temperature and pressure are 140-C and 140 kPa, respectively. Determine the velocities in both sections of the duct.
