Chapter 8, Problem 8.114(choose chapter or problem)
Consider air flowing in a small-diameter steel tube.Graph the Nusselt number associated with fully devel-oped laminar flow with constant surface heat flux for tube diameters ranging from 1?m?D?1 mm.Evaluate air properties at T?350 K and atmosphericpressure. The thermal and momentum accommodation coefficients are ?t?0.92 and ?p?0.87, respectively.Compare the Nusselt number you calculate to thevalue provided in Equation 8.53, NuD4 ? .36.
