A plane wall of thickness 2L = 40 mm and thermal conductivity k = 5 W/m K experiences uniform volumetric heat generation at a rate q, while convection heat transfer occurs at both of its surfaces (x = -L, + L), each of which is exposed to a fluid of temperature T infinity = 20 degree C. Under steady-state conditions, the temperature distribution in the wall is of the form T(x) = a + bx + cx2, where a = 82.0 degree C, b = - 210 degree C/m, c = -2 times 104cC/m2, and x is in meters. The origin of the x-coordinate is at the midplane of the wall. Sketch the temperature distribution and identify significant physical features.
