Consider a tube wall of inner and outer radii r; and r o , whose temperatures are
Question:
Consider a tube wall of inner and outer radii r; and ro, whose temperatures are maintained at Ti and To, respectively. The thermal conductivity of the cylinder is temperature dependent and may be represented by an expression of the form k = ko< 1 + aT), where ko and a are constants. Obtain an expression for the heat transfer per unit length of the tube. What is the thermal resistance of the tube wall?
