1 (40%). Consider a glass screen in top of a small furnace, with a length of 0.7lm and width of 1.02 m. The surface of the glass screen is at a uniform temperature of 232 °C and the room air is at 23 °C. (a) If there is a forced flow at a speed of 5 m/s over and parallel to the top surface, what is the net heating rate from the screen to the room? Include radiation and convection. (b) Compute the radiation heat flux from the room to the screen and show that that is negligible compared to heat flux from the surface.
