Since the pressure losses in corrugated pipe flows are very high, their friction factor was investigated experimentally. Results of measurements of friction factor in laminar to turbulent transition zone of water flow in transverse corrugated pipes having regular roughness of approximately sinusoidal type are presented. The friction factors for four investigated commercially available pipes are increasing asymptotically to some maximum values with rising Reynolds number. Results were obtained for the corrugation depth to minimum diameter ratios, 0.103 ≤ e/d ≤ 0.148 and for the relative corrugation pitch, 0.462 ≥ P/d ≥ 0.270.
