1. Clean Creek is flowing at an average rate of 0.5 m/s. Dirty Corps is importing 30% of the creek water to be used as wash water which is then discharge again to the creek. The upstream of Clean Creek has 20 mg/L of Ca2* and Dirty Corps discharge has seven times as much. Calculate the concentration of calcium ion after the mixing point. in both the stream and waste discharge, the concentration after mixing can be calculated as: CsQs + CwQw = CmQm C- the concentration of selected material (in mass/volume) Q- the volumetric flowrate (volume/time) s,w and m – means stream, waste and mixture conditions respectively where:

Transcribed Image Text:1. Clean Creek is flowing at an average rate of 0.5 m/s. Dirty Corps is importing 30%
of the creek water to be used as wash water which is then discharge again to the creek.
The upstream of Clean Creek has 20 mg/L of Ca2* and Dirty Corps discharge has
seven times as much. Calculate the concentration of calcium ion after the mixing point.
in both the stream and waste discharge, the concentration after mixing can be
calculated as:
CsQs + CwQw = CmQm
C- the concentration of selected material (in mass/volume)
Q- the volumetric flowrate (volume/time)
s,w and m – means stream, waste and mixture conditions respectively
