Problem- Determine the dimensions for a 9-foot deep vertical-wall reservoir with a design flow rate of 13.5 cfs entering the reservoir. The reservoir should be designed to hold stormwater for 30 minutes before overflowing into a stormwater channel. The l:w dimensions are to be 1.5:1.0.
I just need a general explanation of it please- Thanks!
