PART – B

1. Air at 200 kPa and 200°C is heated as it flows through a tube with a diameter of 25 mm at a velocity of 10 m./sec. The wall temperature is maintained constant and is 20°C above the air temperature all along the length of tube. Calculate:
(i) The rate of heat transfer per unit length of the tube.
(ii) Increase in the bulk temperature of air over a 3 m length of the tube. (16)
