Cumec

Cumec

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.
