In statistical mechanics and thermodynamics the compressibility equation refers to an equation which relates the isothermal compressibility and indirect the pressure to the structure of the liquid. It reads center math kT left frac partial rho partial p right 1 rho int d r g r 1 math 1 center where math rho math is the number density, g r is the radial distribution function and math kT left frac partial rho partial p right math is the isothermal compressibility . Using the Fourier representation of the Ornstein Zernike equation the compressibility equation 1 can be rewritten in the form center math frac 1 kT left frac partial p partial rho right frac 1 1 rho int h r d rm r frac 1 1 rho hat H 0 1 rho hat C 0 1 rho int c r d rm r math 2 center where h r and c r are the indirect and direct correlation functions respectively.

Or date March 2011 The acentric factor math omega math is a conceptual number introduced by Pitzer in 1955, proven to be very useful in the description of matter. It has become a standard for the phase characterization of single & pure components. The other state description parameters are molecular weight , critical temperature , critical pressure , and critical volume . The a centric factor is said to be a measure of the non sphericity centricity of molecules. It is defined as math omega log 10 p rm sat r 1, rm at T r 0.7 math . where math T r frac T T c math is the reduced temperature , math p rm sat r frac p rm sat p c math is the reduced pressure saturation of vapor pressure vapors . For many monoatomic, fluids math p r rm sat rm at T r 0.7 math , is close to 0.1, therefore math omega to 0 math . In many cases, math T r 0.7 math lies above the normal boiling point boiling temperature of gases at atmosphere pressure. Values of math omega math can be determined for any fluid from math T r, p r math , and a vapor measurement from math T r 0.7K math , and for many liquid state matter is tabulated into many thermodynamical tables. The definition of math omega math gives zero value for the noble gas es argon , krypton , and xenon . Experimental data yields compressibility factors for all fluids that are correlated by the same curves when math Z math compressibilityfactor is represented as a function of math T r math and math p r math . This is the basis premises of three parameter theorem of corresponding states All fluids at any math omega math value, in math T r, p r const. math conditions, have about the same math Z math value, and same degree of convergence. citation needed date March 2011 See also Equation of state Reduced pressure Reduced temperature References references Category Gas laws ca Factor ac ntric de Azentrischer Faktor es Factor ac ntrico it Fattore acentrico ... more details

Orphan date February 2009 The F factor , in diagnostic radiology , is the conversion factor between rontgen s and rad unit rads or, in more modern units, coulomb s kg to gray unit grays . In other words, it converts between the amount of ionization in air rontgens and the absorbed dose in tissue rads . The two determinants are of the F factor are the atomic number effective Z of the material and the type of ionizing radiation being considered. Since the effective Z of air and soft tissue is approximately the same, the F factor is approximately 1 for many x ray imaging applications. However, bone has an F factor of up to 4, due to its higher effective Z. References Bushberg et al., 2002. The Essential Physics of Medical Imaging.

Shape factor can refer to one of number of values in physics , engineering , or image analysis . Typically, a shape factor refers to a value that is affected by an object s shape but is independent of its dimensions. In physics Shape factor, or shaping factor, a performance measure for filters such as band pass filter s Shape factor X ray diffraction The view factor in the field of radiative heat transfer Shape factor particle physics , denoting the ratio of a elementary particle particle s major dimension to its minor dimension In engineering Shape factor boundary layer flow Structural indices derived from falling weight deflectometer data Compensation for non homogeneity in a compressed or sheared piece is normally provided by a Shape Factor . It is Defined as the ratio between strained or transverse section and free or lateral area. Its usefulness in certain engineering disciplines is demonstrated by the effect which shape can have on the bending and fracture strength of materials tabulating these allows greater accuracy in gauging the usefulness of a material in a given situation. For example, a solid steel bar is very inefficient at resisting deflection and is very heavy for the strength it affords in certain situations, replacing it with an I beam will make for a more efficient design.

Orphan date March 2011 In power engineering , winding factor is what makes the rms generated voltage in a three phase AC electrical generator become lesser. This is because the Armature electrical engineering armature winding of each phase is distributed in a number of slots. Since the Electromagnetic field emf induced in different slots are not in phase, their phasor sum is less than their numerical sum. This reduction factor is called distribution factor K sub d sub . Another factor that can reduce the winding factor is when the slot pitch is smaller than the pole pitch, called pitch factor K sub p sub . The winding factor can be calculated as K sub w sub K sub d sub K sub p sub . Most of the three phase machines have winding factor values between 0.85 and 0.95. With the free online winding editor from http www.eme.ee.kth.se emetor emetor.php Emetor , it is possible to determine the fundamental winding factor as well as the winding factor space harmonics for different winding arrangements as a function of the number of slots and number of poles of the winding.

A scale factor is a number which scaling geometry scales , or multiplies, some quantity. In the equation y Cx , C is the scale factor for x . C is also the coefficient of x , and may be called the constant of proportionality of y to x . For example, doubling distances corresponds to a scale factor of 2 for distance, while cutting a cake in half results in pieces with a scale factor of . The basic equation for it is image over preimage. In the field of measurements, the scale factor of an instrument is sometimes referred to as sensitivity.
