Consider air flowing in a small-diameter steel tube. Graph the Nusselt number associated with fully developed laminar

Question:

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 μm ≤ D ≤ 1 mm. Evaluate air properties at T = 350 K and atmospheric pressure. The thermal and momentum accommodation coefficients are α= 0.92 and αp= 0.87, respectively. Compare the Nusselt number you calculate to the value provided in Equation 8.53, Nu= 4.36.
