In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
All rivers with average discharge more than 15,000 cubic feet per second are listed. Estimates are approximate, because data are variable with time period measured and also because many rivers lack a gauging station near their point of outflow.
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total. This article lists rivers by their average discharge measured in descending order of their water flow rate. Here, only those rivers whose discharge is more than 2,000 m 3 /s (71,000 cu ft/s) are shown. It can be thought of as a list of the ...
In most contexts a mention of rate of fluid flow is likely to refer to the volumetric rate. In hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration ...
The gradual decay in flow after the peaks reflects diminishing supply from groundwater. A hydrograph is a graph showing the rate of flow (discharge) versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in units of cubic meters per second (m³/s) or cubic feet per second (cfs).
If the gas is being released from a closed high-pressure vessel, the above steady state equations may be used to approximate the initial mass flow rate. Subsequently, the mass flow rate decreases during the discharge as the source vessel empties and the pressure in the vessel decreases. Calculating the flow rate versus time since the initiation ...
This list of waterfalls by flow rate includes all waterfalls which are known to have an average flow rate or discharge of at least 150 cubic metres per second (5,300 cu ft/s). The waterfalls in this list are those for which there is verifiable information, and the list should not be assumed to be a complete list of waterfalls which would ...
Mass flow rate (ṁ or μ), the mass of a substance which passes per unit of time Volumetric flow rate ( Q or V ˙ {\displaystyle {\dot {V}}} ), the volume of fluid which passes per unit time Discharge (hydrology) ( Q ), volume rate of water flow that is transported through a given cross-sectional area, such as a river
