Flow Tables for Circular Weirs
Example: Calculating Discharge Over a Circular Weir. Source: Flow in Circular Conduits. PreGenerated Circular Weir Flow Tables. To aid users, Openchannelflow has developed flow (discharge) tables for three medium sized Circular weirs are 2inches H and flow is calculated from of head (the recommended minimum for thinplate weirs) to the top of the circular weir.
