CENAT2 marksNeeds review
The intensity-duration relationship for a rainfall on a rectangular plot ABCD of area 7 ha (1 ha = 10⁴ m²) can be modeled by the following equation:
where I is rainfall intensity (in cm/h), and t is the duration (in minutes) of rainfall. The average runoff coefficient over the area is 0.60. The time of entry (in minutes) to the outfall from the corners A, B, C, and D are 10, 20, 15 and 25, respectively.
The design flowrate (in m³/h) of the storm-sewer at the outfall is _____ (in integer).
