Question

Consider a surface at a uniform temperature of 1000 K. Determine the maximum rate of thermal radiation that can be emitted by this surface, in W/m2.

Answer 1

Answer:

The value is $E_b_{max} = 56.700 *10^{3} \ W/m^2$

Explanation:

From the question we are told that

   The uniform temperature is  $T = 1000 \ K$

Gnerally the rate of thermal radiation is mathematically represented as

         $E_b = \epsilon * \sigma* T^4$

Generally  $\epsilon$  is the emissivity and at maximum the value is  1

                $\sigma$  is the Stefan Boltzmann constant with value  $\sigma = 5.67 *10^{-8} \ W/m^2 \cdot K^4$

So

     $E_b_{max} = 1 * 5.67 *10^{-8}* 1000^4$

=>   $E_b_{max} = 56.700 *10^{3} \ W/m^2$
