An electric power plant consumes 2.5 million gallons per day of cooling water. To control bacterial growth (slime), 2.0 mg/L of chlorine (measured as Cl2) is injected into the make-up water fed to the system. If the specific gravity of liquid chlorine is 3.21, what volume of
liquid chlorine must be stored in order to maintain a 30-day supply?
If the plant uses sodium hypochlorite instead, what volume of NaOCl will be needed? Assume that the dry density of NaOCl is 1.2 kg/L and that 1 mg/L of dissolved NaOCl is equivalent to 1 mg/L of dissolved Cl2.
Note: 1 gal = 3.78 L
