Problem:
The design intake flow of water is 113,500 m3/day. In the water intake structure, you may have intake ports on different water levels. However, at each level you should have enough area of ports such that the intake velocity is equal to or less than the maximum intake velocity when raw water is all withdrawn from ports on the same level.
Required:
Question: Calculate the minimum area of intake ports at each water level that is required in order to avoid trapping aquatic animals and minimize the suspended matter.
