Textbook Question

Chapter 7, Problem 7.49P

A certain wall section is composed of a 12 in. by 12 in. brick area 4 in. thick. Surrounding the brick is a 36 in. by 36 in. concrete section, which is also 4 in. thick. The thermal conductivity of the brick is k = 0.086 lb/sec-°F.

For the concrete, k — 0.02 lb/sec-°F. (a) Determine the thermal resistance of the wall section, (b) Compute the heat flow^r rate through (1) the concrete,

(2) the brick, and (3) the wall section if the temperature difference across the wall is 40°F.
