In light of the results of Problem 7.1, we can assume that fully developed flow is achieved when δ = b. Using a numerical solution method of your choice, solve Eq. (c) in Problem 7.1 and obtain the hydrodynamic entrance length for several values of Re_DH
in the range of 5 × 10³–10⁵. Compare your results with the predictions of the following expression:
