Question:
A slab of polymer 1.6 cm thick, originally at 30°C, is heated between steel plates with a surface temperature of 70°C. The density of the solid is 950 kg/m3, its thermal conductivity is 0.12 W/m · K, and its specific heat is 1,600 J/kg · K.
(a) How long will it take for the centerline temperature to reach 60°C?
(b) What is the average slab temperature at this time?
