Question 1

Which of the following statement(s) is (are) CORRECT?
I. Egg shaped sewers for low discharge maintain hydraulic depth nearly uniform and give 2 to 15% higher velocities than provided by hydraulically equivalent circular sections carrying the same low discharge.
II. In egg shaped sewer the smaller base has to support the weight of the upper broader section, so they are more stable as compared to circular sewer.
