How to Size Gravity Drainage Piping | Sciencing

How to Size Gravity Drainage Piping. When a pipe drains water under gravity, its size limits the flow rate. Wider pipes can carry more water at any time. The pipe''s total capacity also depends on the drainpipe''s length, with longer pipes holding more water at once so
