Consider the cylindrical, 0.12-m-diameter radiationshield
Chapter 9, Problem 9.99(choose chapter or problem)
Consider the cylindrical, 0.12-m-diameter radiationshield of Example 9.5 that is installed concentric with a0.10-m-diameter tube carrying steam. The spacing pro-vides an air gap of L?10 mm.(a) Calculate the heat loss per unit length of the tubeby convection when a second shield of 0.14- mdiameter is installed, with the second shield main-tained at 35?C. Compare the result to that for thesingle shield of the example.(b) In the two-shield configuration of part (a), the airgaps formed by the annular concentric tubes areL?10 mm. Calculate the heat loss per unit lengthif the gap dimension is L? 5 mm. Do you expectthe heat loss to increase or decrease?
