2.60 A plane wall with constant properties is initially at a uni- form temperature T, Suddenly, the surface at x = L is exposed to a convection process with a fluid at T_(>T.) having a convection coefficient h. Also, suddenly the wall experiences a uniform internal volumetric heating q that is sufficiently large to induce a maximum steady- state temperature within the wall, which exceeds that of the fluid. The boundary at x = 0 remains at T T- -k, ģ(120) T_.h (a) On T-x coordinates, sketch the temperature dis- tributions for the following conditions: initial con- dition (t ≤ 0), steady-state condition (→∞), and for two intermediate times. Show also the distribu- tion for the special condition when there is no heat flow at the x = L boundary. (b) On - 1 coordinates, sketch the heat flux for the locations x = 0 and x = L, that is, qX(0, 1) and q(L, 1), respectively.
