Consider air flowing in a small-diameter steel tube. Graph
Chapter , Problem 8.114(choose chapter or problem)
Consider air flowing in a small-diameter steel tube. Graph the Nusselt number associated with fully developed 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 atmospheric pressure. The thermal and momentum accommodation coefficients are t 0.92 and p 0.87, respectively. Compare the Nusselt number you calculate to the value provided in Equation 8.53, NuD 4.36.
