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.

The value is

Explanation:

From the question we are told that

   The uniform temperature is  

Gnerally the rate of thermal radiation is mathematically represented as

Generally    is the emissivity and at maximum the value is  1

                 is the Stefan Boltzmann constant with value  

So

=>
