Peak hourly flow calculation
Webdefinition. Peak hourly flow means, for the purpose of CT calculations, the greatest volume of water passing through the system during any one hour in a day. Peak hourly flow … WebPeak demand is usually the first factor to consider when sizing a distribution system tank. Most water supply sources are best operated on a 24-hour production basis and produce a quantity of water in 24 hours that is equal to the 24-hour demand.
