Problem #3 (30 point): A glass-door fire-screen has a height of 0.8 m and a width of 1.1 m and a temperature of 280°C. The room temperature is 24°C. (a) Estimate the convection heat transfer from the fireplace to the room. Use Churchill and Chu correlation. Is the flow laminar or turbulent. (b) Calculate also the radiation heat transfer from the fire-screen to the room. Assume, emissivity of fire-screen, E: 0.95. Assume, for air at T-425 K: v= 29.4x10m/s, k...
