# Two infinitely large black pla

Two infinitely large black plane surfaces are 0.3 m apart and the space between them is filled by an isothermal gas mixture at 811 K and atmospheric pressure consisting of 25% CO2, 25% H2O, and 50% N2 by volume. If one of the surfaces is maintained at 278 K and the other at 1390 K respectively, calculate
(a) The effective emissivity of the gas at its temperature
(b) The effective absorptivity of the gas to radiation from the 1390 K surface
(c) The effective absorptivity of the gas to radiation from the 278 K surface
(d) The net rate of heat transfer to the gas per square meter of surface area
