Concept explainers
Suppose the insulating qualities of the wall of a house come mainly from a 4.0-in. layer of brick and an R-19 layer of insulation, as shown in Fig. 14-19.What is the total rate of heat loss through such a wall, if its total area is 195 ft2and the temperature difference across it is 35 F°?
Brick Insulation
Problem 45 Two layers insulating a wall.
The rate of heat loss through a wall, if its total area is 195 ft2 and temperature difference is 350 C.
Answer to Problem 44P
Solution:
100 J/s.
Explanation of Solution
The temperature difference is
Area of the wall=195 ft2
So,
