The concentration of ultimate BOD in a river entering the first of two lakes connected in series is equal to 20 g/m³. If the first-order BOD rate coefficient k is 0.35 d-¹ and each lake behaves as a CFSTR, determine the BOD, concentration in the outlet of each lake. The steady-state river flow rate is 4000 m³/d, and the lake volumes are 20,000 and 12,000 m³, respectively.

15mm of precipitation fell in Akkaya reservoir in July. At the beginning of July (30 days), the surface area of the lakewas measured as 3 km². There is 9000000 m³ water in the lake before precipitation in July. At the beginning of August, the water volume in the lake was 8500000 m³. During July, Q=100 lt/s of water emerged from the reservoir. The water leaking from the ground is Q=36 lt/s throughout July. The water leaking in the same month is Q=48 lt/s. In July, 30 lt/s of water was drawn from the reservoir for 15 days to i dilate the campus area. However, in the same month, 1/3 of this water leaked and returned to the lake. During this month, the amount of water evaporating in the lake was determined as 110 mm/ m² .Calculate the flow of water coming into the reservoir as lt/s or m³/s.
A well produces water from a confined aquifer at a rate of 550 m3/day for a period of 30 days, and then the pumping rate decreases to 300 m³/day for another 20 days. What is the resulting drawdown at the well at the end of this 50 day pumping period if T = 50 m²/day, S = 0.001, and the well radius in 0.2 m?
