A velocity water meter Internal structure of a velocity water meter. A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters ...
Travel time meters are generally more accurate than Doppler meters, but only record the velocity between the transducers. Doppler meters have the advantage that they can determine the water velocity at a considerable range, and in the case of an ADCP, at multiple ranges.
Velocity times the cross-sectional area yields a flow rate which can be integrated into volumetric flow. There are two types of area velocity flowmeter: (1) wetted; and (2) non-contact. Wetted area velocity sensors have to be typically mounted on the bottom of a channel or river and use Doppler to measure the velocity of the entrained particles.
This record then serves as an assessment of the volume of water that passes by the stream gauge and is useful for many tasks associated with hydrology. In those instances where a velocity measurement is additionally used as a surrogate, an index velocity determination is conducted. This analysis uses a velocity sensor, often either magnetic or ...

And a substance-like property, — the entropy; for example: One glowing coal won't heat a pot of water, but a hundred will. Energy in thermodynamics is calculated by multiplying the thermal potential by the amount of entropy found at that potential: temperature times entropy. Entropy can be created by friction but not annihilated.
The New York Yankees are bringing in another veteran hitter this offseason, signing first baseman Paul Goldschmidt to a reported one-year, $12.5 million deal, per multiple reports.
Going without health insurance could leave you on the hook for catastrophically large bills. But this year, you may end up paying more for health coverage due to circumstances outside your control.
