Solve the following:
Q: Calculate the heat loss through a 1-m by 3-m glass window 7 mm thick if the inner surface temperature is 20°C and the outer surface temperature is 17°C. Comment on the possible effect of radiation on your answer.
GIVEN
Window: 1 m by 3 m
Thickness (L) = 7 mm = 0.007 m
Surface temperature
Inner (Ti) = 20°C and outer (To) = 17°C
ASSUMPTIONS
One dimensional, steady state conduction through the glass
Constant thermalconductivity
