25 Cfs Water Flow

The terms and definitions below are courtesy of the usgs water science glossary of terms.

25 cfs water flow. Customary unit volumetric flow rate which is equivalent to a volume of 1 cubic foot flowing every second. A cubic foot per second also cfs cu ft s cusec and ft s is an imperial unit u s. For example if you know volume flow rate of some ideal gas at some predefined pressure and temperature like at normal conditions p 101325 pa and t 273 15 k you can calculate actual volume flow rate for pressure and temperature that is actually in the pipe for example the real pressure and temperature in the pipeline is p 30 psi and t 70 f. It also doesn t take into account the temperature of the water and is only accurate for the 40 75 f 4 25 c range.

Gage height the height of the water surface above the gage datum zero point. Usually expressed in cubic feet per second or cfs. Remember that the hazen williams equation is valid only for water applying it for any other fluid will give you inaccurate results. Discharge the volume of water that passes a given location within a given period of time.

Approximately 1 acre foot. The middle fork of the salmon for example is best run at 1 500 5 000 cfs while the lower salmon river is best run around. Approximately 1 acre inch per hour. The standard term for rate of flow of irrigation water is cubic feet per second cfs.

For boaters too much or too little flow can affect the runnability as well as the difficulty posed by a river. Water volume data including cfs readings are collected by agencies like the usgs fish and game bureau of reclamation and other federal and state agencies. Enter 1 0472 in the in the flow rate box and choose cubic feet per second from its menu. Approximately 405 gallons per minute gpm.
