Kerosene is heated by hot water in a shell-and-tube heater. The kerosene is inside the tubes, and the water is outside. The flow is countercurrent. The average temperature of the kerosene is 110°F, and the average linear velocity is 8 ft/so The properties of the kerosene at 110°F are specific gravity 0.805, viscosity 1.5 cP, specific heat 0.583 Btujlb-oF, and thermal conductivity 0.0875 Btu/ft-h-oF. The tubes are low-carbon steel i in. OD by BWG 16. The heat-transfer coefficient on the shell side is 300 Btu/ft2-h-oF. Calculate the overall coefficient based on the outside area of the tube.
