how was calculated the losses in a pipe for the determination of such friction factor. In order to understand how this process worked in practice, an experiment was conducted in a laboratory of the University of Derby. Using a pipe in which water was poured into their beginning and if a route guide at its end which was poured into a tank (Venturi tank). During this course was observed and measured the pressure at various points with different flow rates, so that it was possible…
