Any given point in the pipe or channel per unit time is called the flow rate or discharge (Q). In the U.S., flow rate may be expressed as cubic feet per second (ft3/s or cfs), gallons per minute (GPM), or million gallons per day (MGD). An approximate but convenient conversion to remember is 1 MGD = 1.55 cfs = 700 GPM. ... View This Document
