Question

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 meter length of the tube in steady state, if the thermal conductivity of the tube wall is 10 W/(m·K)?

Step 1

First, we need to find the temperature difference across the tube wall. This is given by: ΔT = T_inner - T_outer ΔT = 800 - 25 ΔT = 550°C Show more…
