Extracted text: (10p) A 15-mm radius pipe is going to be insulated with an insulation material (k=0.1 W/mK). The heat transfer coefficient between the pipe and the surrounding air is 10 W/m?K. What happens to heat transfer rate with respect to no-insulation (bare pipe) case if the thickness of the insulation material is I) 3 mm II) 4 mm III) 6 mm? a. I: decreases, Il: does not change, IlII: increases O D. I: decreases, II: decreases. III: decreases O C. I: increases, II: does not change, Il: decreases Od. I: increases, I: increases, IlI: increases O e. I: does not change, Il: does not change, IlII: does not change
