Question
The intensity-duration relationship for a rainfall on a rectangular plot ABCD of area () can be modelled by the following equation:where is rainfall intensity (in ), and is the duration (in minutes) of rainfall. The average runoff coefficient over the area is . The time of entry (in minutes) to the outfall from the corners A, B, C, and D is and , respectively.The design flowrate (in ) of the storm-sewer at the outfall is _____ (in integer).
Correct answer
300 to 300
Solution
The time of concentration () is the maximum time of entry from any point in the catchment to the outfall.Using the intensity-duration relationship for :Using the Rational Method formula :
Given and .
