Chapter 10, Problem 10.59(choose chapter or problem)
The tube of 10.58 is modified by millingsharp-cornered grooves around its periphery, as inFigure 10.15. The 2-mm-deep grooves are each 2 mmwide with a pitch of S = 4 mm. Estimate the minimumcondensation and heat transfer rates per unit lengththat would be expected for the modified tube. Howmuch is the performance enhanced relative to the orig-inal tube of 10.58?
