Consider the pipe network shown in Figure 7.37. The Hardy Cross method can be used to calculate the pressure distribution in the system, where the friction loss, hf , is estimated using the equation

           hf = rQn

and all pipes are made of ductile iron. What values of r and n would you use for each pipe in the system? The pipeline characteristics are as follows:

Assume that the flow in each pipe is hydraulically rough.
