Question

Heat Transfer Problem?

Here I have a question about heat transfer.
If I put a match vertically above the Bunsen burner with some distance, will the match burn due to convection and radiation?
Thanks!

Answer 1

see below

Explanation:

the heat transferred byradiation dipends from `T_1^4-T_2^4` Where T1 is the temperature in K of the source and T2 the temperature of the receptor. the heat transferred by convetion depends from the differnce `T_1 -T_2` Since in the formulas there are also some coefficients it is no easy to calculate what transmission is the greater, but in first approximation under th3e 300°C is bigger the convetion. Above the 400°C is bigger the radiation. The temperature of air around a bunsen may be 300°C (or less) with reductant and jellow flame,but may be above 1000°C with oxydating blu flame
