1. Diamond Mill Pond located in the South Mountain Reservation is a small pond with a volume of 400 m (1 meter deep, 40 meters long and 10 meters wide). It is fed by a single tributary that has an average flow of 500 L/min The dissolved organic carbon (DOC) concentration in the tributary is 10 mg/L during normal conditions. When water enters the pond the DC is consumed by microorganisms and the decay follows a 1st order process. Reaction rate, r= kCl with a rate constant of 0.001 min-1. a a. If we treat this pond as a steady state completely mixed reactor, what is the effluent concentration of DOC flowing over the Dam. b. If we treat this pond as a steady state plug flow reactor (same retention time as part a, what is the effluent concentration of DOC flowing over the Dam. c. If we treat this pond as two steady state completely mixed reactors of equal size in series, what is the effluent concentration of DOC flowing over the dam
