give me detail answer please

Water vapor condenses on the outside of the tube surface maintaining the inside wall temperature of 488 K. Air flows in the tube and the air is heated by forced convection. The pipe length is 2 m and the inner diameter is 25.4 mm. The air speed is 7.62 m/s and the pressure is 206 kPa. If the bulk temperature of the air is 477K, determine a. convection transfer coefficient, b. Heat flow rate per unit area
