Problem 7 - 64
Determine the flow in each pipe in the figure shown and the elevation of
reservoir C if the inflow to reservoir A is 515 Lit/sec.
Problem 7-64 with the following conditions:
- inflow at reservoir A = 600 Ips
- roughness coefficient for all pipes = 0.05
- elevation B = 92m
The average flowrate at a small municipal wastewater treatment plant is 20,000 m'/d. The highest observed peak daily flowrate is 50,000 m'id. Design rectangular primary clarifiers with a channel width of 6 m. Use a minimum of two clarifiers, Use an overflow rate of 40 m/m d at average flow and a side water depth of 4 m.
4- In a rectangular channel, a hydraulic jump occurs at a point where depth of water-
before and after the jump was 0.6 m and 1.15 m respectively. Determine the
discharge per unit width and critical depth (yc).
