FOR REFERENCE THE R$-$TOTAL FOR THE FIRST $3$ IMAGES IS

Single pane $=\mathrm{.}194$ m$^2*$k$/$W

Doubel Pane $=\mathrm{.}99$ m$^2*$k$/$W

Triple Pane $=1\mathrm{.}786$ m$^2*$k$/$W

Please answer the second part with this information:

The insulation has a given R$-$value, which follows US customary units. Assume constant interior conditions of a convective heat transfer coefficient of $8$ W$/$m$2-$K and a temperature of $72\backslash$deg F$.$Assume the external convec$$ve heat transfer coefficient is constant at $15$ W$/$m$2-$K$.$

a$)$ Draw the wall sec$$on thermal network labelling all characteristics.

b$)$ Calculate the thermal resistance for the wall layers and total section. Present results in a table by breaking wall layer and total thermal resistance.

c$)$ Plot the total heat lost in both BTU$/$hr vs$.$ the external temperature $($F$)$ for each of the three window choices. Secondly, plot Wa$$s vs external temperature $($C$)$ for the three window choices. This is two plots, each with three curves. Temperature range from $0$ F to $100$ F should be covered. Use Excel or MATLAB $$ No hand drawn graphs please.

d$)$ What does the plot show you? $($answer each$)$ What happens at $72$F$?$ How different are the three heat loss scenarios considering the window is only part of the wall? How much heat goes through the insulated wall versus the window? How much additional heat loss is saved by moving from a double pane window to a triple pane window?
