The instructional process at most engineering courses often diverges from real situations, as the learning process moves from the simplest to the most complex problems. In undergraduate mechanical engineering courses, calculation of the operating parameters in a simple branch pumping system operating in transient regime, is a typical example of the gap between the classroom and the field. In the present work, an instructional toolbox is developed to implement a pre-existing analytic solution for this problem, together with a new semi-analytic solution. Those solutions differ by the fact that the former considers the friction factor f to be constant and the last one does not. The use of the toolbox in different applications of academic/industrial interest showed excellent results which is indicative of better knowledge transfer and offers opportunities for discussion and collaboration between students.
