Question

Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 40% of the water is outflow; 49% is seepage; 4% evaporates; and 7% remains as water volume in the ecosystem (Reference: United States Environmental Protection Agency Case Studies Report 832-R-93-005). Chloride compounds as residuals from residential areas are a problem for wetlands. Suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 53.6; seepage, 73.5; remaining due to evaporation, 48.5; in the water volume, 46.8.

Compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (Round your answer to one decimal place.)

Explanation / Answer

required answer is 62.671

weighted average of chlorine compound concentration=sum(f*x)/sum(f)=6267.1/100=62.671

Source percentage(f) chloride compound(x) f*x outflow 40 53.6 2144.00 seepage 49 73.5 3601.50 evaporates 4 48.5 194.00 remains as water 7 46.8 327.60 total 100 6267.1
