Consider a large $3-cm-$thick stainless$-$steel plate in which heat is generated uniformly at a rate of $5{10}^6\frac{W}{m^3}.$ Assuming the plate is losing heat from both sides, determine the heat flux on the surface of the plate during steady operation.

Consider heat loss from a $200-$L cylindrical hot water tank in a house to the surrounding medium. Would you consider this to be a steady or transient heat transfer problem? Also, would you consider this heat transfer problem to be one$-,$ two$-,$ or three$-$dimensional? Explain.

Consider a cold canned drink left on the dinner table. Would you model the heat transfer to the drink as one$-,$ two$-,$or three$-$dimensional? Would the heat transfer be steady or transient? Also, which coordinate system would you use to analyze this heat transfer problem, and where would you place the origin? Explain.

From chapter #$2($slide$\mathrm{.}39),$ divide the thickness of the slab into $10$ equal parts, calculate the temperature at these points, and plot them in an excel sheet to see the temp. distribution along the $x-$direction.
