What is the net radiant interchange per square meter for two very large plates at temperatures 800 K and 500 K respectively? (The emissivity of the hot and cold plates are 0.8 and 0.6 respectively. Stefan Boltzmann constant is $$5.67^* 10^{-8} W/m^2 K^4$$).

A

$$10.26 \frac{kW}{m^2}$$

B

$$1.026 \frac{kW}{m^2}$$

C

$$102.6 \frac{kW}{m^2}$$

D

$$1026 \frac{kW}{m^2}$$
