The designer shall consult with the RHEA = Drainage area, hectares, ha (acres) K u = Units conversion factor equal to 360 (1.0 in English Units) Assumptions inherent in the Rational formula are as follows:(6) • Peak flow occurs when the entire watershed is contributing to the flow. • Rainfall intensity is the same over the entire drainage area.The drainage design calculations. If you are confident doing your own rainwater flow calculations, you'll find the calculator here: calculator.rainclear.co.uk. The outcome of the rainwater drainage design calculation depends on several things: The size of the roof area to be cleared of rain and the pitch of the roof.presented for evaluating rainfall and runoff magnitude, pavement drainage, gutter flow, inlet design, median and roadside ditch flow, structure design, and storm drain piping. Procedures for the design of detention facilities are also presented, along with an overview of storm water pumping stations and urban waterCalculation of peak storm water runoff rate from a drainage area is often done with the Rational Method equation (Q = CiA). Use of Excel spreadsheets for calculations with this equation and for determination of the design rainfall intensity and the time of concentration of the drainage area, are included in this course.2003 corvette convertible anniversary edition
