Torricelli's law describes the parting speed of a jet of water, based on the distance below the surface at which the jet starts, assuming no air resistance, viscosity, or other hindrance to the fluid flow. This diagram shows several such jets, vertically aligned, leaving the reservoir horizontally.
Far Lands or Bust (abbreviated FLoB) is an online video series created by Kurt J. Mac in which he plays the video game Minecraft.The series depicts his journey to the "Far Lands", a distant area of a Minecraft world in which the terrain generation does not function correctly, creating a warped landscape.
In fluid dynamics, the entrance length is the distance a flow travels after entering a pipe before the flow becomes fully developed. [1] Entrance length refers to the length of the entry region, the area following the pipe entrance where effects originating from the interior wall of the pipe propagate into the flow as an expanding boundary layer.
The flow rate varies between 600–950 cubic metres per second (21,000–34,000 cu ft/s) depending on the head available; the greater the head, the less water needed to reach full power. Three Gorges uses Francis turbines with a diameter of 9.7/10.4 m (VGS design/Alstom's design) and a rotation speed of 75 revolutions per minute.

Stream power, originally derived by R. A. Bagnold in the 1960s, is the amount of energy the water in a river or stream is exerting on the sides and bottom of the river. [1] Stream power is the result of multiplying the density of the water, the acceleration of the water due to gravity, the volume of water flowing through the river, and the ...
A normal spillway flow is pressurized by the height of the reservoir above the spillway, whereas a siphon flow rate is governed by the difference in height of the inlet and outlet. [citation needed] Some designs make use of an automatic system that uses the flow of water in a spiral vortex to remove the air above to prime the siphon. Such a ...
Laminar and turbulent water flow over the hull of a submarine. As the relative velocity of the water increases turbulence occurs. Turbulence in the tip vortex from an airplane wing passing through coloured smoke . Smoke rising from a cigarette. For the first few centimeters, the smoke is laminar.
