Cumec
Encyclopedia
The cumec is a measure of flow rate. One cumec is shorthand for cubic metre per second
; also cms or m3/s (m3s−1). Continuing the informal usage, the plural form cumecs is also common in speech.
The cumec is a slang term commonly used between workers in the measurement of water flow through natural streams and civil works, but rarely used in writing. Data in units of cumec are used along the y-axis or vertical axis of the a flow hydrograph
, which describes the time variation of discharge of a river
(the mean
velocity multiplied by cross-sectional area). A moderately sized river discharges in the order of 100 cumecs.
One cumec is equivalent to 35.3147 cubic feet per second in the United States customary units

Cubic metres per second
A cubic metre per second is a derived SI unit of flow rate equal to that of a stere or cube with sides of one metre in length exchanged or moving each second...

River
A river is a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river. In a few cases, a river simply flows into the ground or dries up completely before reaching another body of water. Small rivers may also be called by several other names, including...

United States customary units
United States customary units are a system of measurements commonly used in the United States. Many U.S. units are virtually identical to their imperial counterparts, but the U.S. customary system developed from English units used in the British Empire before the system of imperial units was...
