Problem 3. A stream of air (Pr = 0.72) is heated in fully developed flow through a pipe of diameter D and uniform heat flux q"w. Since the Reynolds number Rep happens to be equal to 2500, there is some uncertainty with regard to the flow regime that prevails in the airstream. Calculate the relative change experienced by the local temperature difference Tw - Tm as the flow regime switches from laminar to turbulent.
