ANALYSIS: The local convection coefficient is obtained from the prescribed correlation, l=Nux-=0.04-Rex pr hx=0.04k 13 ≌分+ To determine the average heat transfer coefficient for the length zero to x, X dx=-C1 x X 0 0 11x 0.1 x09 Hence, the ratio of the average to local coefficient is 1. 11C1X COMMENTS: Note that Nu. /Nuy is also equal to 1. ll.
