AB  - The coefficients of Darcy-Weissbach, Chezy, Hazen-Williams and Manning equations are presented
and calculated as well as the dissipation or loss of the head of each of the equations mentioned by
Simulink/MATLAB. However, the main point is to find the friction factor for Colebrook-White equation which
is easily solved by Simulink/MATLAB which means that it is solved without any complexity or effort. It has
been shown that the Chezy constant is <50 and the Hazin coefficient is <20 and that the Manning coefficient
is always lower than the special friction factor of Darcy-Weisbach for the circular pipe diameter smaller than
or equal to 250 cm.
