Wastewater flow in a sewer can be estimated by adding a known amount of tracer such as salt solution and measuring the salt concentration upstream and downstream of the point of addition. Upstream the background concentration of salt was 50 mg/L. One hundred kilograms of a salt solution (containing 30% salt) per minute was added, and the resulting concentration of salt downstream was determined to be 0.1% salt by weight. Estimate the mass and volumetric flowrate of the wastewater in the sewer.
