Flow rate and velocity are related, but quite different, physical quantities. To make the distinction clear, think about the flow rate of a river. The greater the velocity of the water, the greater the flow rate of the river. But flow rate also depends on the size of the river.
The main characteristic of river runoff is the rate of flow, i.e., the volume of water flowing through the cross-section per unit time (m3/sec). There are several kinds of flow rate: maximum flow rate during high-water periods, minimum flow rate during low-water periods, flow rate at the beginning of spring ice drift, etc. The main sources of ...
We define the rate at which the fluid flows, the volume of fluid passing through the pipe at a particular location along the pipe per second, the volumetric flow rate, \ (I\), sometimes referred to as current: \ [I=\dfrac {dV} {dt}\label {flow-rate}\] with standard SI units of \ (m^3/s\).
Introduction. Water current pervades every facet of existence for life in lotic (flowing water) habitats. Maintaining position in the face of flow can be energetically costly, but provides...
This most commonly identified definition of a river source specifically uses the most distant point (along watercourses from the river mouth) in the drainage basin from which water runs year-around (perennially), or, alternatively, as the furthest point from which water could possibly flow ephemerally.

19 paź 2023 · The energy of flowing river water comes from the force of gravity, which pulls the water downward. The steeper the slope of a river, the faster the river moves and the more energy it has. The movement of water in a river is called a current. The current is usually strongest near the river’s source. Storms can also increase the current.
