• Compression-Controlled Sections These are the sections where the net tensile strain in the extreme tension steel is less than or equal to its yield strain (εy), when the corresponding concrete strain in compression just reaches a strain of 0.003. The value of εy may be taken equal to 0.002 for Grade-420 and all prestressing reinforcement.

1. Design the aeration tank for a sewage flow of 20,000m3/day. The BOD of sewage is 200 mg/L. Adopt an F:M of 0.4 per day and MLSS concentration of 2000 mg/L. 2. An ASP with aeration tank volume of 900 m3 is treating a sewage flow of 4000m3/day with a BOD of 250 mg/L. It is desired to achieve an SVI of
