Does anyone know where I can find Hunter's Curve modified for Stadiums?

I would carefully use Hunter's curve to determine all flow rates and write them down. Then, just as carefully, DOUBLE THE FLOW RATES. A stadium has a boatload of people, and the toilets are ALWAYS FULL AT HALFTIME. Do not be stingy with pipe sizes.

Personally, i would only use hunters curve for non flush valve area sizing (with diversity) and consider the toilet rooms to be more like a dump load. Come half time, virtually all the flush valves are going to be in use nearly simultaneously, thus making values for Hunters very suspect in those areas.

Sloan Valve had a publication where they gave expected flow rates for stadiums based on flush valves. Its an old publication, i.e. pre low flow fixtures so you have to adjust their values, but say for a toilet room with 20 flush valves, you could be looking at 100-120 gpm, just for the toilet room.

Could you please elaborate more why you want the hunter curves? , IMO hunter curves would not be valid for stadiums toilet areas, you have to calculate the flow by yourself, i would gladly help you if you provide more information.
