Question

The Delaware River near Port Jervis, NY has a flow rate of 81 MGD. Pennypack
Creek (a pristine stream) discharges into the river at a flow rate of 3.1 cfs. To study
the mixing of the stream and river, a conservative tracer is to be added to Tin Pot
Run. Assume that no tracer is in the water in the Pennypack Creek, or in Tin Pot
Run above the injection point, and that full mixing occurs by the time the tracer is
measured downstream of the junction. What mass rate of tracer (kg/day) must be
added to Tin Pot Run to achieve a concentration of 1.1 mg/L after complete mixing?
Show all conversion factors.
