Q.8 A circular tube of outer diameter 5 cm and inner diameter 4 cm is used to convey hot fluid. The inner surface of the wall of the tube is at a temperature of 80 °C while the outer surface of the wall of the tube is at 25°C. What is the rate of heat transport across the tube wall per metre length of the tube at steady state, if the thermal conductivity of the tube wall is 10 W/m-K?
