Q2/ 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 5°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= 25 W/m2 °C, and
disregard any heat transfer by radiation.
