A lagoon with volume 15,000 m3 is being polluted by a stream that flows at 1,000 m3/day and carries fecal bacteria with a concentration of 5,000 per mL due to a leaking sewage pipe. a) Assuming this has been going on for a while, that the lagoon is completely mixed (CSTR), and that the bacteria die off with a first-order decay constant of 0.1 day-1, what would be the concentration of the water

Question
Transcribed Image Text:A lagoon with volume 15,000 m3 is
being polluted by a stream that flows
at 1,000 m3/day and
carries fecal bacteria with a
concentration of 5,000 per mL due to
a leaking sewage pipe.
a) Assuming this has been going on
for a while, that the lagoon is
completely mixed (CSTR),
and that the bacteria die off with a
first-order decay constant of 0.1
day-1, what would be
the concentration of the water
flowing out of the lagoon?
