Consider the composite wall of Problem 3.13 under conditions for which the inside air is still characterized
Question:
Consider the composite wall of Problem 3.13 under conditions for which the inside air is still characterized by T ∞.i = 20°C and hi = 30 W/m2 ∙ K. However, use the more realistic conditions for which the outside air is characterized by a diurnal (time) varying temperature of the form
with ho = 60 W/m2 ∙ K. Assuming quasi steady conditions for which changes in energy storage within the wall may be neglected, estimate the daily heat loss through the wall if its total surface area is 200 m2.
