Kerosene is heated by hot water in a shell and tube heat exchanger. The kerosene is inside the tubes and the water is outside. The flow is counter current. The average temperature of the kerosene is 110 °F and the average linear velocity is 8 ft/s. The tubes are low-carbon steel-in. OD BWG 16 (thermal conductivity = 26 Btu/ft.h. °F). The heat transfer coefficient on the shell side is 300 Btu/ft².h. °F. The properties of the kerosene at 110 °F are Specific gravity = 0.805 Viscosity = 1.5 CP Specific heat = 0.583 Btu/lb.°F Thermal conductivity = 0.0875 Btu/ft.h. °F a. Calculate the overall heat transfer coefficient based on the outside surface area of the tube.

Question
Kerosene is heated by hot water in a shell and tube heat exchanger. The kerosene is inside the tubes and the water is outside. The flow is counter current. The average temperature of the kerosene is 110 °F and the average linear velocity is 8 ft/s. The tubes are low-carbon steel 2-in. OD BWG 16 (thermal conductivity = 26 Btu/ft.h. °F). The heat transfer coefficient on the shell side is 300 Btu/ft².h. °F. The properties of the kerosene at 110 °F are Specific gravity = 0.805 Viscosity = 1.5 CP Specific heat = 0.583 Btu/lb.°F Thermal conductivity = 0.0875 Btu/ft.h. °F a. Calculate the overall heat transfer coefficient based on the outside surface area of the tube.
