Benzene is cooled from 141 to 79℉ (60.6 to 21.1℃) in the inner pipeof double-pipe exchanger. Cooling water flows countercurrently tothe benzene, entering the jacket at 65℉ (18.3℃) and leaving at 75℉(23.9℃). The exchanger consists of an inner pipe of 78-in. (22.2-mm)BWG 16 copper tubing jacketed with 112-in. (38.1-mm) Schedule 40steel pipe. The linear velocity of the benzene is 5 ft/s (1.52m/s).Neglecting the resistance of the wall and scale films and assumingL/D > 150 for both pipes, compute the film coefficients of thebenzene and water and the overall coefficient based on the outsidearea of the inner pipe
