Minimum velocity in sewer pipe

WebThe self-cleansing slope is a function of the Manning constant, pipe diameter, ratio of actual flowrate to full flowrate, and self-cleansing velocity. It is found that current recommended minimum slopes correspond to an actual velocity of 0.45 m/s when the actual flowrate is approximately 15% of the full flowrate.
