Radiation Heat Transfer:
- When heat transfer takes place through electro magnetic waves between two bodies isolated together in a vacuum, the phenomenon is called radiation
- The rate at which the energy is radiated by a black body at temperature T is given by Stefan-Boltzman law
Q = σ A T4
Where
Q = rate of energy radiation, watt
A = surface area radiating heat, m2
σ = Stefan-Boltzmann constant, 5.67x10-8 W/m2k4
