| 520 | _aHead loss gradient is used to give an estimate for C factor for aged pipes. Equation of Colebrook and White for C factor determination based in age and final roughness height is entered in Watergems coding area to be calculated within Wategems interface. The chorine decay and C factor relationship is studied. The effect of C factor in leakage also falls under the scope of this research. The relation of diameter reduction in aged pipes diameter to the corresponding C factor is inferred | ||
