Hydraulic jump characteristics [7] [8] [13] [15] Amount upstream flow is supercritical (i.e., prejump Froude Number) Ratio of height after to height before jump Descriptive characteristics of jump Fraction of energy dissipated by jump [11] ≤ 1.0: 1.0: No jump; flow must be supercritical for jump to occur: none 1.0–1.7: 1.0–2.0: Standing ...
Running vertical jump: This refers to a vertical jump after a run up: the last step of the run is used to launch into the jump. This may help to add additional energy to the jump and improve on the standing vertical jump result. [2] In general, the standing vertical jump is the one that is used as an official measurement for athletes. [1]
The height of the hydraulic jump, similar to length, is useful to know when designing waterway structures like settling basins or spillways. The height of the hydraulic jump is simply the difference in flow depths prior to and after the hydraulic jump. The height can be determined using the Froude number and upstream energy. Equations:
A plaque on Vasil Levski National Stadium, Sofia, Bulgaria, commemorating Valeriy Brumel's high jump world record of 2.25 m set on 31 August 1961. The first world record in the men's high jump was recognized by the International Association of Athletics Federations (IAAF) in 1912. As of June, 2009, the IAAF has ratified 40 world records in the ...
A jump harness is often employed in training quads. [51] Quads require an average rotational frequency of around 340 rpm, with the peak rotational frequency usually exceeding 400 rpm. [52] The optimum height is estimated to be around 51 cm (20 in); [53] however, most skaters rarely go above 46 cm
Jurin's law, or capillary rise, is the simplest analysis of capillary action—the induced motion of liquids in small channels [1] —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter.
In the example jump-off, the final cleared height is 1.88m, at which A B C and D each have one failure. D has two failures at lower heights compared to one each for the other three, who proceed to a jump-off at the next height above the final cleared height. C is eliminated in the second round of the jump-off 1.89m, then B wins in the third round.
Ski jumping is a winter sport in which competitors aim to achieve the farthest jump after sliding down on their skis from a specially designed curved ramp.Along with jump length, competitor's aerial style and other factors also affect the final score.
