## Hydraulics: Check the Comparisons

Values for the coefficient of roughness of pipe have been investigated for many years. Extensive data are available on this subject. Presently accepted values for the coefficient of roughness may appear to be sufficient but, an understanding of how these values were determined is important. The value that is needed is the one which will accurately predict the hydraulic properties of the field installations during service life.
