## Compare Flow Description
Compare Flow app uses Manning's Formula, the most widely accepted formula for evaluating the hydraulic capacity of non-pressure sewers.

In order to evaluate possible alternatives in either pipe geometry or material, use this app to compare the hydraulic flow capacity among various concrete pipes including circular, elliptical, arch and box sections with circular thermoplastic and corrugated metal pipes.
