- 1The velocity of flow is always lower than in a hydraulically equivalent circular sewer at low discharges
- 2The larger base supports the structural load of the smaller upper crown section
- 3The smaller invert base provides a higher hydraulic radius at low discharge to maintain self-cleansing velocity✓
- 4The top and bottom sections have equal structural stiffness
Correct answer
The smaller invert base provides a higher hydraulic radius at low discharge to maintain self-cleansing velocity
