Calculate the thermal gradient of a wall section provided and draw the temperature gradient. $(T_{\text{o}\text{u}\text{t}}=0C$;

and $T_{in}=20C,$ and all the resistance value for each layer has been given.

For a basement in State College, PA$,$ its dimension $(20$x$30$x$5)$ is shown in the figure. Fill out the two

tables below about the heat loss of the walls and the floor, respectively.

Mean winter outdoor temperature: $T_{\text{a}\text{v}\text{e}}=33F$

Amplitude of the group temperature: $A_{\text{s}\text{o}\text{i}\text{l}}=18F$

Basement temperature setting: $T_{\text{b}\text{a}\text{s}\text{e}\text{m}\text{e}\text{n}\text{t}}=65F$
