Chapter 5, Problem 5.57(choose chapter or problem)
In a tempering process, glass plate, which is initially ata uniform temperature Ti, is cooled by suddenly reduc-ing the temperature of both surfaces to Ts. The plate is20 mm thick, and the glass has a thermal diffusivity of610?7m2/s.(a) How long will it take for the midplane temperatureto achieve 50% of its maximum possible tempera-ture reduction?(b) If (Ti?Ts)?300C, what is the maximum tem- perature gradient in the glass at the time calculatedin part (a)?
