1.	Kerosene is heated by hot water in a shell-and-tube heater. The kerosene is inside the tubes, and 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 properties of the keroseneat 110F are specific gravity, 0.805, viscosity is 15 P. specific heat 0.583 Btu/Ib F and thermal conductivity, 0.0875 Btu/fth F. The tubes are low-carbon steel 3/4 in OD byBWG 16. The heat-transfer coefficient on the shell side is 300 Btu/ftaF. Calculate theoverall coefficient based on the outside area of the tube 165cal g
Answer» Answer: 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/s. The properties of the kerosene at 110°F are: specific gravity, 0.805; viscosity, 1.5 cP; specific heat, 0.583 Btu/lb · °F; and thermal conductivity, 0.0875 Btu/ft · h · °F. The tubes are low-carbon steel -in. OD by BWG 16. The heat-transfer coefficient on the shell SIDE is 300 Btu/ft2 · h · °F. Calculate the overall coefficient based on the outside AREA of the tube.
