Consider two very large parallel plates. The bottom plate is warmer than the top plate, which is held at a constant temperature of T1 330 K. The plates are separated by L 0.1 m, and the gap between the two surfaces is filled with air at atmospheric pressure. The heat flux from the bottom plate is q 250 W/m2.
(a) Determine the temperature of the bottom plate and the ratio of the convective to radiative heat fluxes for 1 2 0.5. Evaluate air properties at T 350 K.
