| Roughness coefficient is an effective factor on water velocity and discharge in drain pipes. Roughness coefficient in experimental box model with dimensions of 100×41×56cm was evaluated with two pipes of smooth and corrugated in a diameter of 63 and 56mm by three series of independent tests. The first set was done on pipes with mineral envelop, the second set on pipes with synthetic materials and the third one on pipes without envelop. The mean values of "n" Manning’s in the smooth pipe with synthetic and mineral envelope and non-envelop materials were measured 0.0106, 0.0111, 0.011, and for the corrugated pipe 0.0088, 0.009, 0.0091. The mean values of "n" Ganguillete-Kutter’s in the smooth pipe with synthetic and mineral envelop and non-envelop materials were obtained 0.0048, 0.0048, 0.0048, and for the corrugated pipe 0.0041, 0.0042, 0.0042. The "n" values from the Reynolds-Darcy Weissbach combination formula in the smooth pipe with synthetic and mineral envelop and non-envelop materials were calculated to be 0.0050, 0.0050, 0.0049 and for the corrugated pipe 0.0048, 0.0048, 0.0049. Two evaluation indexes (R2 and RMSE Error Value) indicated a better result for n value obtained by Ganguillet-Kutter formula. The flow inside the drainage pipes is a turbulent and spatially variable which is affected by the small flows entering the pipe through holes. This flow pattern, while disrupting the uniform distribution of the transverse velocity of the flow, caused flow inhibition and increased Manning's roughness coefficient in the first 30 cm due to the flow rate and low flow speed compared to the second 30 cm. The negligible difference between "n" Manning’s with "n" Ganguillete-Kutter’s is not important and applying 0.011 for Manning coefficient in smooth pipe and 0.009 for corrugating pipe with envelop is satisfactory. | ||
