Question
Example 2: Double-pane window, each window have: Height = 0.8 m
Width 1.5 m
Thickness = 4 mm
k (glass) = 0.78 W/m.K
separation between two glasses (air) = 10 mm
k (air) = 0.026 W/m.K
Temperature of inner surface = 20°C
Temperature of outer surface = -10°C
Convection heat transfer coefficient on the inner surface h1= 10 W/m2·°C Convection heat transfer coefficient on the outer surface h2= 40 W/m2·°C Determine the heat transfer through the window?
Transcribed Image Text:Example 2: Double-pane window, each window have:
Height = 0.8 m
Width 1.5 m
Thickness =4 mm
k (glass) = 0.78 W/m.°K
separation between two glasses (air) = 10 mm
k (air) = 0.026 W/m.°K
Temperature of inner surface = 20°C
Temperature of outer surface = -10°C
Convection heat transfer coefficient on the inner surface h1= 10 W/m².°C
Convection heat transfer coefficient on the outer surface h2= 40 W/m².°C
Determine the heat transfer through the window?
