Angular diameter print that page


The angular diameter or apparent size of an object as seen from a given position is the “visual diameter” of the object measured as an angle. In the vision sciences it is called the visual angle . The visual diameter is the diameter of the perspective projection of the object on

Diameter tape print that page


A Diameter tape (D-tape)is a form of dendrometer that consists of a cloth or metal tape that is mainly used to measure diameter at breast height (DBH). DBH is measured at a fixed height of 4.5 feet (137.16 cm) above the ground, where it is most convenient to measure diameter . DBH is

Beam diameter print that page

The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be obtained in many different ways. Five definitions of the beam

Gauge (bore diameter) print that page


The gauge of a firearm is a unit of measurement used to express the diameter of the barrel . Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm, and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a

Hydraulic diameter print that page

The hydraulic diameter , D H , is a commonly used term when handling flow in noncircular tubes and channels. Using this term one can calculate many things in the same way as for a round tube. Definition: where A is the cross sectional area and P is the wetted perimeter of the cross
