Reconsider Prob. 9-21. Using EES (or other) software, plot the amount of heat loss through the glass as a function of the window glass thickness in the range of 0.1 cm to 1.0 cm. Discuss the results.
Problem 9-21
The inner and outer surfaces of a 0.5-cm thick 2-m 2-m window glass in winter are 10°C and 3°C, respectively. If the thermal conductivity of the glass is 0.78 W/m · K, determine the amount of heat loss through the glass over a period of 5 h. What would your answer be if the glass were 1 cm thick?
