$16$ MLD of water is flowing through a $2.5$ km long pipe of diameter $45$ cm. The chlorine at the rate of $32$ kg/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, $n=1$. The minimum amount of chlorine (in kg per day) to be applied to achieve the same degree of disinfection for the enhanced flow is

  1. $60.50$
  2. $44.00$
  3. $38.00$
  4. $23.27$
