A steam pipe is intended to be insulated with two layers of insulating materials of different thermal conductivities. For minimum heat transfer to take place

A The better insulation material should be put just next to pipe (i.e., inside)
B The better insulating material should be put outside
C Either of the insulating material could be put on either side
D Steam temperature is considered before deciding as to which insulating material is to be put inside (i.e., just next to the pipe)

Correct Answer: The better insulation material should be put just next to pipe (i.e., inside)
