Question

Consider a curing kiln whose walls are made of 0.02 m thick concrete with a thermal diffusivity of α = 0.23 × 10−5 m2/s. Initially, the kiln and its walls are in equilibrium with the surroundings at 6°C. Then all the doors are closed and the kiln is heated by steam so that the temperature of the inner surface of the walls is raised to 42°C and the temperature is maintained at that level for 11.5 h. The curing kiln is then opened and exposed to the atmospheric air after the steam flow is turned off. Determine the temperature of the outer surface of the walls at 11.5 h.

The temperature of the outer surface of the walls at 11.5 h is

The image depicts a cross-sectional view of a heat-insulated cuboidal structure. The structure has two distinct temperature regions: 1. The outer blue section is marked with a temperature of 6°C. 2. The inner blue section, which is enclosed by the outer section, is marked with a temperature of 42°C. This visual is likely used to illustrate the gradient of temperature between two layers in a thermally insulated object. The outer layer maintains a lower temperature (6°C), while the inner core remains significantly warmer (42°C), demonstrating how effective insulation maintains different temperature zones within a single body. Such diagrams are useful in educational contexts for explaining principles of thermal insulation, heat transfer, and temperature gradients.
