16 MLD of water is flowing through a $2.5 \mathrm{~km}$ long pipe of diameter $45 \mathrm{~cm} .$ The chlorine at the rate of $32 \mathrm{~kg} / \mathrm{d}$ is applied at the entry of this pipe so that disinfected water is obtained at the exit. There is a proposal to increase the flow through this pipe to 22 MLD from 16 MLD. Assume the dilution coefficient, $\mathrm{n}=1 .$ The minimum amount of chlorine (in $\mathrm{kg}$ per day) to be applied to achieve the same degree of disinfection for the enhanced flow is
(A) 60.50
(B) 44.00
(C) 38.00
(D) 23.27
