2. Volumetric flow rate - Wikipedia

   en.wikipedia.org/wiki/Volumetric_flow_rate

   The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .

3. Flow coefficient - Wikipedia

   en.wikipedia.org/wiki/Flow_coefficient

   Q is the rate of flow (expressed in US gallons per minute), SG is the specific gravity of the fluid (for water = 1), ΔP is the pressure drop across the valve (expressed in psi). In more practical terms, the flow coefficient C v is the volume (in US gallons) of water at 60 °F (16 °C) that will flow per minute through a valve with a pressure ...

4. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   This depth is converted to a flow rate according to a theoretical formula of the form = where is the flow rate, is a constant, is the water level, and is an exponent which varies with the device used; or it is converted according to empirically derived level/flow data points (a "flow curve"). The flow rate can then be integrated over time into ...

5. Hazen–Williams equation - Wikipedia

   en.wikipedia.org/wiki/Hazen–Williams_equation

   S foot of water per foot of pipe; P d = pressure drop over the length of pipe in psig (pounds per square inch gauge pressure) L = length of pipe in feet; Q = flow, gpm (gallons per minute) C = pipe roughness coefficient; d = inside pipe diameter, in (inches) Note: Caution with U S Customary Units is advised. The equation for head loss in pipes ...

6. Miner's inch - Wikipedia

   en.wikipedia.org/wiki/Miner's_inch

   The miner's inch is a method of measuring the amount of flow a particular water supply system (such as a flume or sluice) is capable of supplying. The miner ’s inch measures the amount of water that would flow through a slot of a given area at a given pressure (for example, at a head of 6 inches of water , or 1.5 kPa .)

7. K-factor (fire protection) - Wikipedia

   en.wikipedia.org/wiki/K-factor_(fire_protection)

   In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.

8. Cubic metre per second - Wikipedia

   en.wikipedia.org/wiki/Cubic_metre_per_second

   Cubic metre per second or cubic meter per second in American English (symbol m 3 ⋅ s −1 or m 3 /s) is the unit of volumetric flow rate in the International System of Units (SI). It corresponds to the exchange or movement of the volume of a cube with sides of one metre (39.37 in) in length (a cubic meter, originally a stere) each second.

9. Discharge (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Discharge_(hydrology)

   The rate of flow is typically expressed in units of cubic meters per second (m³/s) or cubic feet per second (cfs). Hydrographs often relate changes of precipitation to changes in discharge over time. [3] The term can also refer to a graph showing the volume of water reaching a particular outfall, or location in a sewerage network. Graphs are ...
