Question

Transcribed Image Text:Consider a 0.8 m and 1.5 m wide double pane window consisting of two (5) mm thick layers of glass (k = 0.78 W/m.k) separated by a (11) mm wide stagnant air space
(k= 0.026 W/m.k). Determine the steady rate of heat transfer through this double-pane window and the temperature of its inner surface (T₁) for a day during which the
room is maintained at (23)°C while the temperature of the outdoors is (-12)°C. Take the convention heat transfer coefficients on the inner and outer surfaces of the
window to be h₁ = 10 W/m². °C and h₂ = 40 W/m². °C, which includes the effects of radiation.

Note:
1. To calculate the heat transfer rate, you need to calculate individual thermal resistance and finally total resistance.
2. Please enter your answers to 2 significant figures.
