#### Solution Preview

I have solved this problem by calculating different thermal resistances and heat loss then by using it we can calculate interior temperature.

As given in problem

There is no radiation heat transfer so there will be no effect of e.

Interior heat transfer is given as

hi = 40 W/m2 K

ho = 30 W/m2 K

So overall heat transfer coefficient

1/h = 1/ hi + 1/ho

= 1/40 +1/30

= 7/120

h = 120/7

h = 17.14 W/m2 K

Now we will calculate thermal resistances

Then thermal resistance at surrounding will ...

#### Solution Summary

The thermal circuit of brick and plaster heat transports are examined. The circuit combining brick and plasters are provided.
