You manage a drinking water system. Chlorine (hypochlorous acid: HOCl) is added to the water to protect it from recontamination during distribution. To this end, it is recommended that the water at the customer tap is more than 0.2ppm (precisely). A schematic of the distribution system is shown below. After treatment and disinfection, a portion of the water is chlorinated and blended with non-chlorinated water to achieve the desired level of HOCl. Assume the entire system shown below has reached steady-state. Given (note that the units are part of the variables): 1. The reservoir may be considered a well-mixed system. 2. The reaction (decay) rate constant for HOCl is 0.0017042sec1, the decay reaction occurs both in the distribution lines and the reservoirs. 3. The volume of the reservoir is 455,114m3, 4. The distribution lines have a velocity of D=1.45m/s before the reservoir and G=0.093m/s after. A=3.48m3/sec;B=89,908mg/L;C=1,072m3/sec;H=75.9m (a) What is the concentration of HOCl (in mg/L ) in the stream coming out from the Drinking Water Treatment Plant pipe at the inlet to the reservoir? (Write your answer up to 3 significant digits.) (b) What is the concentration of HOCl (in mg/L ) in the Water Reservoir? (Write your answer up to 4 significant digits or one decimal point.)
