The tube of 10.58 is modified by milling sharp-cornered
Chapter , Problem 10.59(choose chapter or problem)
The tube of 10.58 is modified by milling sharp-cornered grooves around its periphery, as in Figure 10.15. The 2-mm-deep grooves are each 2 mm wide with a pitch of S 4 mm. Estimate the minimum condensation and heat transfer rates per unit length that would be expected for the modified tube. How much is the performance enhanced relative to the original tube of 10.58?
