Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as: [ 1 ] G F = Δ R / R Δ L / L = Δ R / R ε = 1 + 2 ν + Δ ρ / ρ ε {\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac ...
A thousandth of an inch is a derived unit of length in a system of units using inches.Equal to 1 ⁄ 1000 of an inch, a thousandth is commonly called a thou / ˈ θ aʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils).
Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. Thus air pressure varies with location and weather . If the entire mass of the atmosphere had a uniform density equal to sea-level density (about 1.2 kg/m 3 ) from sea level upwards, it would terminate abruptly at an altitude of 8.50 ...
When oil is produced to surface temperature and pressure it is usual for some natural gas to come out of solution. The gas/oil ratio (GOR) is the ratio of the volume of gas ("scf") that comes out of solution to the volume of oil — at standard conditions.
Coronagraph image of the Sun. A coronagraph is a telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise would be hidden in the object's bright glare – can be resolved.
Kepler-80, also known as KOI-500, is a red dwarf star of the spectral type M0V. [2] This stellar classification places Kepler-80 among the very common, cool, class M stars that are still within their main evolutionary stage, known as the main sequence.
Phred quality scores shown on a DNA sequence trace. A Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing.
