F = Factor for fractionation allowable velocity P = Column pressure, psia T = Tray spacing, in. [Pg.61]

The resonance line from the 130 keV state is a factor of 5 narrower than that from the 99 keV transition and therefore more amenable to isomer shift studies. However, even at 20 °K, the 130 keV transition recoilfree fraction, f = 2.8%, is much smaller than that of the 99 keV transition, and the effect observed with a 0.011-inch absorber is only 0.26% (10).

P = Pressure, psia for fractionator F factor correlation or psig for vessel thickness calculation [Pg.225]

E = efficiency of motor and pump expressed as a fraction f = Fanning friction factor, dimensionless, or function for dynamic programming in Eq. (91) indicating optimum return depends on that input [Pg.413]

The intensity of the Mossbauer effect is determined by the recoil-free fraction, or f factor, which can be considered as a kind of efficiency. It is determined by the lattice vibrations of the solid to which the nucleus belongs, the mass of the nucleus, and the photon energy, E0 and is given by [Pg.123]

Otherwise, i f j / k and after rearrangement and introduction of different fractional scaling factors the following equation results [Pg.224]

This paper will summerize our experimental data on the equilibrium factor (F), the free fraction (f ), the attachment rate to the room air aerosol (X), the recoil factor r and the plateout [Pg.289]

Dg, Dl = vapor and liquid phase diffusion coefficients, m /s liL = liquid holdup, mm / = fractional approach to flood Fya = active area F-factor, Uap (active area = bubbling area of tray) [Pg.467]

The inclusion or omission of the permittivity of free space, So in these equations does not affect the discussion of the integer or simple fractional numerical factors, although it does change the units in which F or are reported (see Appendix).] Optical theory then relates the 2m polarization to the observed second harmonic intensity. Assuming that F has been correctly determined in terms of the fields as defined in (7.1) it has then to be expressed in terms of the molecular parameters. [Pg.260]

If, instead of assuming diffuse reflection at the wall, it is postulated that a fraction f of the incident molecules is scattered diffusely and the rest suffer specular reflection, the right hand side of equation (2.8) must be multiplied by a factor (2 - f)/f. [Pg.9]

The Rayleigh distillation equation was developed to mathematically describe this t5q>e of cumulative isotope effect. It relates the initial (Rq) and transient (RJ stable isotope ratios of a reservoir to the fraction (f) of the initial material that remains (often expressed at the concentration ratio, Q/Cq of the more abundant isotope) when product is removed with a constant fractionation factor, a, over a time, t [Pg.151]

The environmental conditions for each of the cases considered below are summarized in Table III all these parameters are constant in time. The build up of the nucleation mode of the stable particles and the build up of both the nucleation and accumulation modes of the radon decay products is calculated, and the results are given after a process time of one hour. Figures 1 to 5 show the size distributions of stable and radioactive particles, and Table IV gives the disequilibrium, the equilibrium factor F, the "unattached fraction" f and the plate-out rates for the different daughters.
