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