2. Froude number - Wikipedia

   en.wikipedia.org/wiki/Froude_number

   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.

3. Standard step method - Wikipedia

   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.

4. Hydraulic jumps in rectangular channels - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_Jumps_in...

   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 ...

5. Asbestos abatement - Wikipedia

   en.wikipedia.org/wiki/Asbestos_abatement

   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.

6. Asbestos - Wikipedia

   en.wikipedia.org/wiki/Asbestos

   Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -⁠toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...

7. Friability - Wikipedia

   en.wikipedia.org/wiki/Friability

   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.

8. Fanno flow - Wikipedia

   en.wikipedia.org/wiki/Fanno_flow

   For given upstream conditions at point 1 as shown in Figures 3 and 4, calculations can be made to determine the nozzle exit Mach number and the location of a normal shock in the constant area duct. Point 2 labels the nozzle throat, where M = 1 if the flow is choked. Point 3 labels the end of the nozzle where the flow transitions from isentropic ...

9. Asbestos cement - Wikipedia

   en.wikipedia.org/wiki/Asbestos_cement

   Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet"; but different from the natural mineral fibrolite), or AC sheet, is a composite building material consisting of cement and asbestos fibres pressed into thin rigid sheets and other shapes.
