Answer:
65.7 mg/l.
Step-by-step explanation:
Answer:
A. 65.7 mg/l.
B. iv. No. The average chlorine compound concentration (mg/l) is too high.
Step-by-step explanation:
Given:
Outflow = 36%
= 36 l in 100 l of wetland
Seepage = 47%
= 47 l in 100 l of wetland
Evaporates = 8%
= 8 l in 100 l of wetland
Water volume = 9%
= 36 l in 100 l of wetland
Outflow = 53.6 mg/l
Seepage = 73.9mg/l
Remaining due to evaporation = 57.0mg/l
Water volume = 74.0 mg/l
Concentration of Chlorine compounds:
Outflow = 36/100 * 53.6
= 19.3 mg/l of outflow chlorine in the wetlands.
Seepage = 47/100 * 73.9
= 34.73 mg/l of seepage chlorine in the wetlands.
Evaporates = 8/100 * 57
= 4.56 mg/l of evaporates chlorine in the wetlands.
Water volume = 9/100 * 74
= 6.66 mg/l of outflow chlorine in the wetlands.
Weighted average concentration of chlorine compounds in 100 l of wetland = total(X*W)/totalW
Where,
Total w = 0.36 + 0.47 + 0.08 + 0.09
= 1
Total X*W = 19.3 + 34.73 + 4.56 + 6.66
= 65.65/1
= 65.7 mg/l.
