3 cards from this section. Quick, good the night before a test.
What is the typical range for flow velocity in sewers?
Look for the numbers mentioned in the section.
Define self-cleansing velocity.
Think about what makes pipes clean.
What is the minimum self-cleansing velocity required for sewage flow?
Recall the number mentioned in the section.
True or False: A steep sewer slope always helps maintain a good flow.
Think about balance and what the section stated.
Given a sewer system with a flow velocity of 0.5 m/s and a slope of 0.5%, identify potential issues that may arise and recommend design alterations.
Think about how speed affects sediment.
Calculate the necessary diameter for a sewer line designed to carry a peak flow of 50 liters/second with a desired flow velocity of 1 m/s.
Recall the formula for flow area!
