Fig. 3From: Modeling of residual chlorine in a drinking water network in times of pandemic of the SARS-CoV-2 (COVID-19)Variation of kw as a function of the velocity for the different diameters. a For diameter pipelines: 160, 200 and 250 mm b For diameter pipelines: 63 and 110 mm. These figures indicate that the chlorine decay rate with the wall is limited by the water flow velocity in the pipelinesBack to article page
