Chapter 4, Problem 4.53P

A long conducting rod of rectangular cross section ( 20 mm × 30 mm ) and thermal conductivity k = 20 W/m K experiences uniform heat generation at a rate q . = 5 × 10 7 W/m 3 , while its surfaces are maintained at 300 K.

  1. Using a finite-difference method with a grid spacing of 5 mm, determine the temperature distribution in the rod.
  2. With the boundary conditions unchanged, what heat generation rate will cause the midpoint temperature to reach 600 K?

A truncated solid cone is of circular cross section, and its diameter is related to the axial coordinate by an expression of the form D = ax3/2, where a = 2 m−1/2.       The sides are well insulated, while the top surface of the cone at x1 is maintained at T1 and the bottom surface at x2 is maintained at T2. Conductivity k = 336 W/m-K (a) Obtain an expression for the temperature distribution T(x). (b) What is the rate of heat transfer across the cone if it is constructed of pure aluminum with x1 = 0.086 m, T1 = 113°C, x2 = 0.270 m, and T2 = 25°C?
The temperatures on the faces of a plane wall 20 cm thick are 400 and 90 ℃. The wall is constructed of a special glass with the following properties: k = 0.8 W∙m-1K-1, ρ = 2750 kgm-3, cP = 0.86 kJkg-1K-1. What is the heat flux (q") through the wall at steady-state conditions?
A metal composite wall consists of two outer metal skins (k = 100 W/m.k) 2 mm thick which sandwich an insulating composite (k = 15 W/m.k). If the composite material is 96 mm thick, and the temperature difference across the outer metal skins is 75 degree celsius, state the heat flux q to the nearest kW.
