A small catchment is drained by a pipeline 400m long to the sea. 5 straight manholes are used as junction boxes with the first manhole at the inlet. The sea level is 1m below the ground level. Determine whether flooding will occur if the design discharge is 0.3m3 /s, the pipe diameter is 600mm, the Darcy friction coefficient is 0.04, and the exit loss coefficient Ke=1.0. If flooding occurs, determine the appropriate diameter of the pipes to eliminate flooding.
