Pipe Sizing for Storm Drain Performance - Insights from the IAPMO/ASPE White Paper

The Authority Podcast: Plumbing and Mechanical

Join IAPMO experts Dan Cole and Christoph Lohr for a technical exploration of storm drainage system design and the critical equations engineers need to calculate effect flow rates through piping.
Among the key insights is the impact of pipe material on flow velocity. For instance, PVC and cast iron pipes of the same size can have vastly different flow capacities. Dan and Christoph discuss the key differences between the Manning and Darcy-Weisbach equations, why current plumbing code tables may not tell the whole story, and how proposed code changes could give designers more accurate tools for material selection.
In an era where storms are increasing causing urban flooding from excessive rainfall events, this episode will help engineers to make informed decisions for accurate storm drainage system sizing and ensure optimal performance and longevity.
