Minimum velocity in sewer pipe
WebThe velocity of flow through sewers can be determined using Manning’s formula as below: v 1 2/3 1/2 r s n Where, (1) v = velocity of flow in the sewer, m/sec r = Hydraulic mean depth of flow, m = a/p a = Cross section area of flow, m2 p = Wetted perimeter, m n = Rugosity coefficient, depends upon the type of the channel surface i.e., material and WebMinimum velocity • It is important for sewers to be able to convey wastewater or stormwater without long-term deposition of solid material. • This is normally achieved by specifying a minimum mean velocity, a so …
