The Clearwater water treatment plant uses sodium hypochlorite (NaOCl) to disinfect the treated water before it is pumped to the distribution system. The NaOCl is purchased in a concentrated solution (52,000 mg/L) that must be diluted before it is injected into the treated water. The dilution piping scheme is shown in Figure P-2-6. The NaOCl is pumped from the small tank (called a “day tank”) into a small pipe carrying a portion of the clean treated water (called a “slip stream”) to the main service line. The main service line carries a flow rate of 0.50 m^3/s. The slip stream flows at 4.0 L/s. At what rate of flow (in L/s) must the NaOCl from the day tank be pumped into the slip stream to achieve a concentration of 2.0 mg/L of NaOCl in the main service line? Although it is reactive, you may assume that NaOCl is not reactive for this problem.
