Suppose you wished to cut the heat loss through the wall in Exercise in half by installing insulation. What thickness of Styrofoam should be placed between the fiberboard and concrete block to accomplish this goal
Exercise
The wall of a house is composed of a solid concrete block with an outside brick veneer and is faced on the inside with fiberboard, as illustrated in Fig. If the outside temperature on a cold day is 10 °C and the inside temperature is 20 °C, how much energy is conducted through the wall in 1.0 h if it measures 3.5 m by 5.0 m
FIGURE Thermal conductivity and heat loss See Exercise.
