As far as I understand, you have to plot <span>t(v) = v/k.
According to this, you have to use a form like that </span>
, in which 
.
Then you can see that the vertical-intercept is zero therefore the gradient should be is <span><span>1/k.
Do hope you will find my both answer helpful and useful. Regards!</span></span>

Answer:
Q=7200 W
q=7200/72=100
Explanation:
Given that
ΔT=15° C
Thickness ,t=15 cm
Thermal conductivity ,K=1 W/m.°C
Height,h=6 m
Length ,L=12 m
As we know that heat conduction through wall given as
Now by putting the values
A= 6 x 12 =72
Q=7200 W
Q is the total heat transfer.
Heat flux q
q=Q/A
q=7200/72=100
q is the heat flux.
As w know that heat flux(q) is the heat transfer rate from per unit area and on the other hand heat transfer(Q) is the total heat transfer from the surface.
Heat flux q=Q/A
That is why these both are different.
