A pipe carrying saturated steam is covered with a layer of insulationand exposed to ambient air.

The thermal resistances are as shown in the figure.Which one of the following statements is correct in this regard? 
  • a)
    Rsream and Rpipe are negligible as compared to Rins and Rair
  • b)
    Rpipe and Rair are negligible as compared to Rins and Rsteam
  • c)
    Rsteam and Rair are negligible as compared to Rpipe and Rins
  • d)
    No quantitative data is provided, therefore no comparison is possible.
Correct answer is option 'A'. Can you explain this answer?
