Hydraulic design of drainage pipes: Simplified solution

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


A simple equation simulating flow in sub-surface drain pipe was developed and solved. The solution is based on the assumption that both velocity and pressure are continuous functions of distance along the drain length. The velocity head was also considered negligible. The solution was compared to results obtained from available design charts and procedures. The developed equation can be directly applied mainly to design drain laterals.
