2. Draw the solution of the equation on an x-t diagram showing the position of the peak of concentration and the end of the tail clearly 3. At what time will the peak reach the Murray bridge, exactly 450 km downstream of the measuring point at Renmark? 4. What will be the concentration of toxic waste at the Murray bridge 112.6 hours after the peak of the toxic waste passes Renmark?
Concentration (c) ū -1000m Om Distance Along the River from Renmark (x) Figure 6: Murray river (left) and measured toxic concentrations along a stretch of river (right), where x=0 is located exactly at Renmark and negative implies upstream of Renmark. 400mg/l (peak)
