Assume constant values for the conductivity and density of the materials; where appropriate, state the values used in the problems and your source for the information. 2. Apply Fourier's law to determine the steady state heat temperature distribution, the heat flux vector and total flux across a 5 mm thick square sheet, 10 cm on a side, of a) aluminum b) alumina under the condition that the left boundary is maintained at 100o C and the right side is at 0o C. Left and right are in the direction perpendicular to the sheet. Ignore edge effects.
