To improve indoor air quality, an Edinburgh pub has installed a vertical glass screen to cover the opening of its fireplace. The square-shaped screen has a side of length 1.5 m and a surface temperature of 232°C. Determine the heat transfer from the fireplace to the room if the ambient and wall temperatures are both 22°C and the emissivity of the glass surface is 0.9. (Use the following for air: k = 3.38 x 10-2 W/mK, v = 2.641 x 105 m?/s, Pr = 0.690.) %3D
