We use a simple example of incompressible turbulent flow as a means of introducing engineering students to turbulent flow without recourse to a physical description of the different regimes of wall bounded turbulent flows or the rigor of asymptotics, both of which are necessary and appropriate in an advanced engineering course (see, for example, [9]). Here, we use an empirical polynomial approximation of fully developed streamwise velocity profile in a plane channel due to Pai [2]. This problem has been the focus of major experimental and computational analysis in the second half of the twentieth century and continues to reveal novel microscopic features thanks to increased supercomputing resources.
