Abstract: To characterize the flow in a flow, standard textbook method is to solve the modified Bernoulli's energy balance equation and the Colebrook friction equation simultaneously, using an iterative method prone to numerical errors.A better way is a graphical method where the equations are plotted on a Moody's chart and the solution derived by locating the intersection(s) of relevant curves.This paper introduces a new Matlab app for such purpose and demonstrates its capability to find (i) flow velocity and (ii) pipe diameter, given all other relevant parameters.The graphical method is extended to drag force on an immersed object.
