Question: Air is heated as it flows subsonically through a 10 cm = 10 cm square duct. The properties of air at the inlet are maintained

Air is heated as it flows subsonically through a 10 cm = 10 cm square duct. The properties of air at the inlet are maintained at Ma1 = 0.4, P1 = 400 kPa, and T1 = 360 K at all times. Disregarding frictional losses, determine the highest rate of heat transfer to the air in the duct without affecting the inlet conditions.
