3. An architect is interested in estimating the heat loss (in kcal/s) through a sheet of insulating material as a function of the thickness of the sheet. Assuming fixed temperatures on the two faces of the sheet, which one of the graphs in the figure best represents the rate of heat transfer as a function of the thickness of the insulating sheet?

The graph that best represents the rate of heat transfer as a function of the thickness of the insulating sheet is

  • Graph C

The equation can be given as,

[tex]\frac{dQ}{dt} = \frac{kA(\delta T)}{L}[/tex]

As heat transfer varies inversely as the thickness, then the answer is graph C
