A composite wall is shown below:

Assume steady$-$state conditions with no heat generation or air movement in any part of the wall,

neglect radiation, and determine:

a$)q^{\text{'}\text{'}}(\frac{W}{m^2})$ through the entire wall;

b$)$ Temperature at each interface

c$)$ Calculate the thermal resistance of the system.

d$)$ Calculate, U$,$ the overall heat transfer coefficient.

e$)$ Explain how to use this calculation technique to determine proper size for an air

conditioner for the entire building. Indicate factors other than conduction that must be

considered when sizing an air conditioner.

f$)$ If radiation is significant with emisivity of bricks $=0\mathrm{.}88$ and effective Tsur $=100F,$ find the

surface temperature of outer brick and q$"$ through wall.
