Consider the following statements about fin effectiveness. Which are true? Select all that apply.

Fin effectiveness increases with increasing convection coefficient.

Fin effectiveness compares the heat transfer rate through the fin to that of the bare surface without the fin.

Fin effectiveness is given as Rconv/Rfin Fin effectiveness tells you if a fin design is any good.

Fin effectiveness increases with increasing thermal conductivity.

Answer 1

Fin effectiveness compares the heat transfer rate through the fin to that of the bare surface without the fin.

This question is based on formula only and states the effecriveness of fin comapred to the case when fin is not used.

Statement 2 is correct
