Thermal conductivity wall board: 0.028, fiberglass batts: 0.019, stonce concrete: 0.54, building brickwork: 0.4, oak layer: 0.12

hi=ho=12W/m^2K

please calculate heat flux with and without oak layer :) thanks will give like if correct

Before insulation is added: After insulation is added: The thermal conductivities are provided in Appendix 11 in the textbook. For the purposes of this oroblem, you may assume that the convective heat transfer coefficients for both the inside of the wall board and the outside of the brick hi and ho are 12W/m2K. (a) First assume that the inner temperature is heated and kept at 70F. First assume that the additional insulation is filled in with oak wood. In the winter, assuming that we are in Southwest Michigan and the exterior temperature is approximately 32F, calculate the heat flux q/A in Btu/(hrft2) with and without the oak layer. Then calculate all of the temperatures at each interface in F and label them on a similar diagram as above.
