A two-cell intake tower located in a cold climate reservoir is being designed for a winter design flow rate of 6,000 rr/d. The tower will have three ports at three different elevations in each cell. Each port must be able to deliver the design flow rate operating alone. Determine the area of each port opening, A two-cell intake tower located in a cold climate reservoir is being designed for a winter design flow rate of 6,000 rr/d.
