ABSTRACT

Water/wastewater treatment plants consist of a series of tanks and channels. Proper operational control requires the operator to perform several process control calculations involving parameters such as the circumference, perimeter, area, or volume of a tank or channel. Many process calculations require computation of surface areas. To aid in performing these calculations, the following definitions are provided:

Area-The area of an object, measured in square units. Base-The bottom leg of a triangle, measured in linear units. Circumference-The distance around an object, measured in linear units.
