Dynamic Water Water In Motion

Compared to the study of fluid flow at rest, the study of fluid flow (water in motion) is much more complicated, but it is important to have an understanding of these principles because the water in a water treatment and distribution system is nearly always in motion. Discharge is the quantity of water passing a given point in a pipe or channel during a given period of time. It can be calculated by the formula:

where:

Q = discharge in cubic feet per second (cfs).

V = water velocity in feet per second (fps or ft/s).

A = cross-section area of the pipe or channel in square feet (ft2).

The discharge can be converted from cfs to other units such as gallons per minute (gpm) or million gallons per day (MGD) by using the appropriate conversion factors.
