Calculational Coefficients related to a change of state of common light components. [Pg.419]

The basic form of the equation is normally modified so that the differential is expressed in pressure units and the flow coefficient is divided into the product of an experimentally deterrnined discharge coefficient, iC, and a series of calculated coefficients. In this form, for concentric restrictions ... [Pg.59]

From these correlations it is possible to calculate the film heat transfer coefficient and the pressure loss for laminar flow. This coefficient, combined with that of the metal and the calculated coefficient for the service fluid together with the fouling resistance, is then used to produce the overall coefficient. As with turbulent flow, an... [Pg.398]

Similar experiments were conducted with deuterium. Comparing the results of these experiments with those obtained with protium, a conclusion was made that the ratio of calculated coefficients of surface diffusion of these particles is close to Vz. In other words, this ratio is a manifestation of a usual isotopic shift for diffusivity given by as one might expect assuming that surface diffusion... [Pg.241]

During a screening campaign some plates and even entire batches can fail due to various reasons. To control the quality of plates, during a screen, we use the Z-primes and the Multivariate Z-primes nodes we have developed. Plates failing to fulfill a minimal criterion such as a Z-prime factor above 0.3 are eliminated from further analysis and scheduled for rescreening. A further useful node to verify the quality of plates is the CV node that calculates coefficients of variance for selected parameters. [Pg.118]

A quadratic equation was found to fit the crushing strength values the best compared to other Scheffe models [31]. The calculated coefficients of the quadratic model equation (21) are presented in Table 4.4. [Pg.185]

Models in general are a mathematical representation of a conceptual picture. Rate equations and mass balances for the oxidants and their reactants are the basic tools for the mathematical description. As Levenspiel (1972, p.359) pointed out the requirement for a good engineering model is that it be the closest representation of reality which can be treated without too many mathematical complexities. It is of little use to select a model which closely mirrors reality but is so complicated that we cannot do anything with it. In cases where the complete theoretical description of the system is not desirable or achievable, experiments are used to calculate coefficients to adjust the theory to the observations this procedure is called semi-empirical modeling. [Pg.127]

The hard sphere diameters were then used to calculate the theoretical Enskog coefficients at each density and temperature. The results are shown in Figure 3 as plots of the ratio of the experimental to calculated coefficients vs. the packing fraction, along with the molecular dynamics results (24) for comparison. The agreement between the calculated ratios and the molecular dynamics results is excellent at the intermediate densities, especially for those ratios calculated with diameters determined from PVT data. Discrepancies at the intermediate densities can be easily accounted for by errors in measured diffusion coefficients and calculated diameters. The corrected Enskog theory of hard spheres gives an accurate description of the self-diffusion in dense supercritical ethylene. [Pg.20]

Venlafaxine concentrations in plasma (C ), in the plasmatic free fraction (CpLpp) and in oral fluid (C ), plasmatic or plasmatic free fraction/oral fluid concentration ratios (R0FIPL or / FF, respectively) and the calculated coefficients of determination (r2) for CQF vs. CpL or CpL pp (n = 4) (Source From de Castro A et al.

The data for reaction (viii) refer to the sum (kg + fega)- Flame computation suggests kg < 0.1 kg. Using the data given, the sum of the rate coefficients at room temperature is approximately twice the maximum value of (kg + kg + 20) = 2 x lO found by Albers [186], The discrepancy is removed if both the calculated coefficients are multiplied by 1.5 exp (-330/T). [Pg.143]

The mathematics can be applied directly to generate linear combinations over resultant local functions modulated by calculated coefficients in order to construct all the possible group orbitals for an orbit decorated with valence atomic orbitals, or the mathematics can be applied to generate only one half of the number of possible linear combinations over resultant local functions, while the remaining group orbitals are obtained from these by concerted local rotations of the local resultants of the first set, or... [Pg.108]
