ENVIRONMENTAL ENGINEERING Problem #1:A 225-mm sewer is to flow full at velocity of 0.75 m/sa) What are lits maximum capacity and what minimum grade it should be laid if coefficient ofroughness is 0.013.b) How many people it can serves if the Peak average per capita flow is 300 lpcd. Ignoreinfiltration) How many additional people the sewer can cater if slope is doubled Problem #2:A 700,000 m² watershed is 30 percent Agricultural and 70 % urban. The agricultural land is 40 %cultivated with conservation treatment, 35 % meadow in good condition, and 25 % forest landwith good cover. The urban area is residential: 60 % on 1350 m² lots, 25 % on 1000 m² lots, and15 % streets and roads with curbs and storm sewers. The soil group is B. Determine a compositeCN and the total discharge from a 150 mm for 24- hour storm duration.

Note: Since you have asked multiple questions, we will solve the first question for you. If you want…
