The Froude number is used to compare the wave making resistance between bodies of various sizes and shapes. In free-surface flow, the nature of the flow (supercritical or subcritical) depends upon whether the Froude number is greater than or less than unity. One can easily see the line of "critical" flow in a kitchen or bathroom sink.
To help visualize the relationship of the upstream Froude number and the flow depth downstream of the hydraulic jump, it is helpful to plot y 2 /y 1 versus the upstream Froude Number, Fr 1. (Figure 8) The value of y 2 /y 1 is a ratio of depths that represent a dimensionless jump height; for example, if y 2 /y 1 = 2, then the jump doubles the ...
In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when those materials are being removed, encapsulated, or repaired.
Consequently, this depth corresponds to a Froude Number of 1. Depths greater than critical depth are considered “subcritical” and have a Froude Number less than 1, while depths less than critical depth are considered supercritical and have Froude Numbers greater than 1.
Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. [1] Due to rising oil prices, these methods are often less expensive than an asphalt overlay and last three times longer in addition to providing a greener, more sustainable solution. [2] [3] [4]
Figure 4: An undular front on a tidal bore. At this point the water is relatively deep and the fractional change in elevation is small. A tidal bore is a hydraulic jump which occurs when the incoming tide forms a wave (or waves) of water that travel up a river or narrow bay against the direction of the current. [16]
In addition to reducing the number of parameters, non-dimensionalized equation helps to gain a greater insight into the relative size of various terms present in the equation. [ 1 ] [ 2 ] Following appropriate selecting of scales for the non-dimensionalization process, this leads to identification of small terms in the equation.
