Consider the net radiant heat flux between an object and its
surroundings as given by
qrad,net = ǫ σ ( T4 − T ∞4 ) (
1 ) where ǫ is the emissivity, σ is the Stefan-Boltzmann constant
(5.670374419×10−8 in
W ), T is the object’s temperature and T is the surrounding
(ambient) temperature. m2K4 ∞
1-a) Linearize qrad,net in terms of ǫ, T, and T∞, use deviation
variables and call this expression qL′ .
1-b) Compute the value for...
