WebThis particular method has been used successfully in many high-rise building designs. Supplying adequate water pressure at all levels of the building is critical for building occupants, although economics, basic building functions, and overall heights have significant impact on methods of water supply distribution. WebMethod is a simple model used to estimate the peak flow from a given watershed. For applications such as backyard stormwater practices, where small, highly impervious watersheds will be treated, the Rational Method offers a somewhat coarse, but adequate, estimate of peak flow. The Rational Method is as follows: Equation 3-3: Rational Method
