The Rappahannock River near Warrenton, VA, has a flow rate of 2.9 m³/s. Tin Pot Run (a pristine stream) discharges into the Rappahannock at a flow rate of 0.08 m³/s. To study mixing of the stream and river, a conservative tracer is to be added to Tin Pot Run. If the instruments that can measure the tracer can detect a concentration of 1.0 mg/L, what minimum concentration in mg/L must be achieved in Tin Pot Run so that 1.0 mg/L of tracer can be measured after the river and stream mix? Assume that the 1.0 mg/L of tracer is to be measured after complete mixing of the stream and Rappahannock has been achieved and that no tracer is in Tin Pot Run or the Rappahannock above the point where the two streams mix. Draw a control volume with streams in and out labeled appropriately. Write out the general mass balance equation as the starting point for determining the answer. (Round your answer to the nearest whole number.) Type:
