    Slopes in the clear zone should be at most 1:4, and should typically be 1:6. Curbs: No curb is to be placed nearer to the roadway than the outside edge of the paved shoulder. Any curb is to have a sloping, and not a vertical face, and be no more than 4 inches (10 cm) in height. Special care should be taken when curbs are combined with barriers.

  3. Tree height measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_height_measurement

    The height of the tree above eye level is [h1 = sin(a) x D1]. The same process is used to measure the height or extension of the base of the tree above or below eye level where D1 is the distance to the base of the tree and (b) is the angle to the base of the tree.

    The LCL can be either computed or determined graphically using standard thermodynamic diagrams such as the skew-T log-P diagram or the tephigram.Nearly all of these formulations make use of the relationship between the LCL and the dew point, which is the temperature to which an air parcel needs to be cooled isobarically until its RH just reaches 100%.

    The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.

  7. Wind gradient - Wikipedia

    en.wikipedia.org/wiki/Wind_gradient

    It is the rate of increase of wind strength with unit increase in height above ground level. [ 5 ] [ 6 ] In metric units, it is often measured in units of meters per second of speed, per kilometer of height (m/s/km), which reduces inverse milliseconds (ms −1 ), a unit also used for shear rate .

  8. Tree volume measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_volume_measurement

    [28] [29] The volume of the trunk is expressed as a percentage of the volume of a cylinder that is equal in diameter to the trunk above basal flare and with a height equal to the height of the tree. A cylinder would have a percent cylinder occupation of 100%, a quadratic paraboloid would have 50%, a cone would have 33%, and a neiloid would have ...
