Hey guys, can you please help my solve this?? Thanks

One of the typical examples of a mixing problem is a lake, with a polluted river flowing in and another river flowing out. If we knew the concentration of pollutant in the first river, and the flows of each of the rivers, and the amount of water in the lake, it would be fairly straightforward to use the techniques of Section 2.2 to solve for an equation giving the concentration of pollutant in the lake at any given time (and even calculate the exact time when the pollutant concentration would be so high as to necessitate evacuation of the fish!). List three "real-world" factors that might make our mathematical model inaccurate.

Explanation / Answer

1.The concentration of pollutant is not generally uniform in the water.

2.The exact amount of water in the lake is not known as it depends on the externl environment conditions such as Temperature.

3.The flow rate is also not known accurately depending on various factors such as usage of water from rivers for electricity etc
