Grade is usually expressed as a percentage - converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for flat, to 100% at 45 ...
V is velocity (in ft/s for US customary units, in m/s for SI units) k is a conversion factor for the unit system (k = 1.318 for US customary units, k = 0.849 for SI units) C is a roughness coefficient; R is the hydraulic radius (in ft for US customary units, in m for SI units) S is the slope of the energy line (head loss per length of pipe or h ...
For example, the code ft has link Foot (unit), but unit psi/ft needs ft to be linked to Fracture gradient. To handle such cases, a unit code starting with " - " is used ( -ft-frac for feet with a link to fracture gradient).
{{convert|123|cuyd|m3+board feet}} → 123 cubic yards (94 m 3; 40,000 board feet) The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked.
The biggest dry land area below sea level that has been known to exist during the geological past, as measured by continuous volume of atmospheric air below sea level, was the dry bed of the Mediterranean Sea of the late Miocene period during the Messinian salinity crisis.
Cross slope is the angle around a vertical axis between: the horizontal line that is perpendicular to the road's center line, and; the surface. Typical values range from 2 percent for straight segments to 10 percent for sharp superelevated curves.
Time for a new pair of Skechers? These blend style, comfort, and ease. With a breathable mesh design, slip-on convenience, and cushioned memory foam insoles, they'll keep you comfy all day long.
For example, given that H s is 10 metres (33 feet), statistically: 1 in 10 will be larger than 10.7 metres (35 ft) 1 in 100 will be larger than 15.1 metres (50 ft) 1 in 1000 will be larger than 18.6 metres (61 ft) This implies that one might encounter a wave that is roughly double the significant wave height.
