Q2. Consider 1D heat transfer across a slab with thermal conductivity k and thickness L. The steady state temperature is of the form T-Ax'+Bx+Cx+D. Find expressions for the heat generation rate per unit volume in the slab and heat fluxes at the two wall faces (i.e. x=0, L). please find the expressions for the heat generation rate in the wall and the heat fluxes at the two wall faces(x-0, L). (20 points) Assumptions: (1) steady state conditions, (2) one-dimensional heat flow, (3) homogeneous medium.
