In designing a sewer an engineer selects a diameter of 300 mm and a slope that yields a
velocity of 0.6 m/s when flowing full. This design satisfactorily handles the flow rate at
the end of the design period with self-cleansing action. However, he neglected to check
the operating conditions at the beginning of the design period, when the flow rate is
expected to be 10 L/s. Assuming n = 0.013, find:
a)
The actual velocity when q = 10 L/s
b)
If there is self-cleansing at q = 10 L/s. If the answer is no,
c)
Find the slope that should be used to have self-cleansing at the beginning of the
design period.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3ae357a1-da80-4d8d-b2eb-00b0628180fd%2Fbea945dc-7945-4887-b272-d23f479a8337%2Fsg2xx9r_processed.jpeg&w=3840&q=75)
