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.arrow_forwardHope your help hydraulic CEE 340arrow_forward
