How can there be more flow in a pipe than its full capacity? #SWMM5 and #InfoSWMM - Emoji View

๐ŸŒŠ๐ŸŒ€ Unraveling the Pipe Capacity Enigmas of #SWMM5, ICM InfoWorks & ICM SWMM ๐Ÿš€๐ŸŒ

๐Ÿ“Œ Spotlight on Innovyze: Our enlightening journey today seamlessly blends knowledge from the Innovyze blog, tailored especially for the champions of #SWMM5, ICM InfoWorks, and ICM SWMM! ๐Ÿ”๐Ÿ”— Innovyze Blog Post

๐Ÿค”๐Ÿ’ก Puzzling Pipe Phenomenon: Ever had those perplexing moments ๐Ÿ™†‍♂️ when, within #SWMM5 or ICM platforms, a surcharged pipe's maximum simulation flow exceeds its full capacity? Sounds baffling, right? How does more water flow than the pipe's capacity? ๐ŸŒŠ๐Ÿ”

๐Ÿ“Š Deciphering Qfull: In #SWMM5 and its ICM counterparts, Qfull (from the link input summary table) is sourced from the revered Manning's equation ๐Ÿ“œ. While this equation is foundational, it's a tad simpler than the intricate St Venant equations ๐Ÿงฎ harnessed by the engines of SWMM5, ICM InfoWorks, and ICM SWMM for model outputs. This leads to minor variances between Qfull (dictated by slope) and the actual flow discharge as determined by the 1D St Venant Equations. Crucial insight: Qfull serves as a handy reference for us, the users ๐Ÿง‘‍๐Ÿ’ป, and isn't the engine's yardstick for determining pipe surcharge. ๐Ÿ–ฅ️๐Ÿ”—

๐Ÿง Manning's Equation Unveiled: Manning's equation paints a picture of a pipe that stretches limitlessly ๐ŸŒŒ. Resultantly, it's common for a pipe to ferry more water than its nominal capacity sans surcharge. Want a litmus test? ๐Ÿ•ต️‍♂️ Extend your pipe or stick to a constant max flow, and voilร , brace yourself for the surcharge spectacle! ๐ŸŒŠ๐ŸŽข

๐Ÿ“✨ The Influence of Length: Pipe length isn't just a number; it's a game-changer! ๐Ÿš€ A nimble 10-meter pipe might effortlessly channel a flow that its 100-meter sibling grapples with, even if they mirror each other in gradient, roughness, and other traits. It all boils down to friction loss, which magnifies with length! ๐Ÿ“ˆ๐Ÿ”ฅ

๐ŸŽ‰๐ŸŽˆ Golden Nuggets: As stewards of water ๐Ÿ’ง and aficionados of #SWMM5, ICM InfoWorks, and ICM SWMM, it's pivotal to fathom that every modeling marvel, be it SWMM or ICM, amalgamates both time-tested wisdom and sophisticated computations. At times, they might seem at odds, but a deeper dive (literally!) can illuminate and elevate our comprehension! ๐ŸŒŸ๐Ÿ“š๐ŸŒ
