Understanding Infrared Thermography Reading 3

R c is easier to use than h when determining combined conductive and
convective heat transfer because then they are additive terms.
In real terms, this expression means that the rate of convective heat flow
increases with increasing temperature difference, increases with higher
convective heat flow coefficient and decreases with increasing convective
thermal resistance.
Conductive and convective heat transfer are very similar. In both, the heat
transfer is directly proportional to the temperature difference and the speed at
which th is energy is transferred (rate of heat flow) depends on the transfer
coefficient of the media or material through which the heat energy flows. By
comparison, radiative heat transfer takes place in accordance with a different
set of rules.
