Effect of the Distribution System on Drinking Water Quality	2001	3	.pdf	application/pdf	2579	165	55	The overall rate of chlorine decay can be expressed as follows: � ��c b f H w� � � �k k R c c where � is the rate of chlorine decay in mg�l�1 �d��, kb first order decay coefficient in d��, c chlorine concentration in bulk flow in mg�l�1, kf mass transfer coefficient in m�d�1, RH hydraulic radius in m, cw chlorine concentration at the pipe wall in mg�l�1. 3 Modeling of chlorine decay The first method for the decrease in chlorine in the bulk flow is based on first order kinetics [3]: c c k t t e� � � 0 1 where ct is the chlorine concentration in time t, in mg�l��, c0 chlorine concentration in time t = 0, in mg�l��, t time in days, k1 first order decay coefficient in d�1.	cache/ap-222.pdf	txt/ap-222.txt
