Q1:1
Consider a 1.2-m-high and 2-m-wide glass window whose thickness is 6 mm
and thermal conductivity is k = 0.78 W/m °C. Determine the steady rate of heat transfer
through this glass window and the temperature of its inner surface for a day during which
the room is maintained at 24°C while the temperature of the outdoors is 56 °C. Take the
convection heat transfer coefficients on the inner and outer surfaces of the window to be
h₁= 10 W/m² °C and h₂= 38 W/m² °C, and disregard any heat transfer
by radiation.
