Before the carrying out of the design for the expansion of a water distribution system, it is preferable to verify whether the nodal consumption and the roughness coefficient of pipe lines assumed are consistent with the present field condition of the system. The prograrn #774 was prepared for this particular purpose. In this paper, the fundamental principles upon which the program was compiled and the methods of its applications are fully discussed.

Nowadays it is in the disign of the water distribution system of filters that empirical data is widely used.
