Use the use the p concentration in tap water you calculated in question 4, and the mass balance equation from question 5 to calculate the steady-state concentration of p in prospect park lake (i. e., clake). assume q = qin = qout = 0.15 m3 /s, asurface = 55 acres, and �& =10 m/yr. if you are unsure of your answer to question 4, you can use a concentration of p in tap water (i. e., cin) equal to 0.8 mg/l
