Calculate the overall heat-transfer coefficient of a steel pipe based on the inside area. The inside diameter of the pipe is 10 cm, and the pipe is 2 cm thick. The inside convective heat- transfer coefficient is 350 W/(m2 o C), the outside convective heat-transfer coefficient is 25 W/(m2 o C), the thermal conductivity of the steel pipe is 15 W/(m C). If the pipe is used to convey steam at a bulk temperature of 110 o C and the outside ambient temperature is 20 o C, determine the rate of heat transfer from the pipe.
