The formula to convert Gallons Per Minute (GPM) to Cubic Feet Per Second (CFS) is:
\[ \text{CFS} = \text{GPM} \times \left( \frac{0.133681}{60} \right) \]
Where:
Gallons per minute (GPM) is a unit of flow rate that indicates the number of gallons of liquid that flow out of a system in one minute. It is commonly used in the United States to measure the flow rate of water in plumbing systems, irrigation systems, and other fluid transport systems.
Cubic feet per second (CFS) is a unit of flow rate that indicates the volume of fluid passing a point in a system per second. It is commonly used in hydrology, river engineering, and environmental engineering to measure the flow of water in rivers, streams, and other open channels.
Example 1:
Using the formula:
\[ \text{CFS} = 500 \times \left( \frac{0.133681}{60} \right) = 1.114 \text{ cubic feet/second} \]
Example 2:
Using the formula:
\[ \text{CFS} = 1000 \times \left( \frac{0.133681}{60} \right) = 2.228 \text{ cubic feet/second} \]
