Air at a pressure of 101.3 kPa and 288.8 K enters inside a tube having an inside diameter of 12.7 mm and a length of 1.52 m with a velocity of 24.4 m/s. Condensing steam on the outside of the tube maintains the inside wall temperature at 372.1 K. Calculate the convection coefficient of the air. (Note: This solution is trial and error. First assume an outlet temperature of the air.)

Air at a pressure of 101.3 kPa and 288.8 K enters inside a tube having an inside diameter of 12.7
mm and a length of 1.52 m with a velocity of 24.4 m/s. Condensing steam on the outside of the
tube maintains the inside wall temperature at 372.1 K. Calculate the convection coefficient of the
air. (Note: This solution is trial and error. First assume an outlet temperature of the air.)
