Water enters a small copper tube, with an inner diameter of 2.5 cm, at the rate of 0.025 kg/s and a temperature of 15°C. Steam is condensing on the outer surface of the tube at atmospheric pressure so that tube-surface temperature is uniformly at 100°C. If the tube length is 5 meters, determine 

(a) The outlet temperature

(b) The average convection heat transfer coefficient between the water and the pipe.
