Sentence examples for factor fraction from inspiring English sources
Field recovery factor, fraction.
The relation between the desirability function (d i ) and the factor fraction (X i ) is divided sectionally as the desirability scale, see Fig. 1.
The scale of desirability emphasises a relationship between the affecting factor via factor fraction (X i ) and the desirability function by the intervals of the desirable degree.
However, due to the idealized detector model used, this effect is not included in Equation 5. Furthermore, the buildup factor (fraction of scattered to direct radiation) is assumed to be approximately constant over the area of the projected pore.
The Harrington's function (Harrington 1965) is proposed to use as a desirability function (see Fig. 1); d_{i} = e^{{ - e^{{ - X_{i} }} }} (3)where X i is the factor fraction depending on its desirability: Open image in new window Fig. 1 The Harrington's function used as a desirability function (d).
According to Eq. (3), the individual desirability (d i ) of each effecting factor is calculated by substituting its factor fraction (X i ) using the Harrington's function according to Eq. (3): Factor: oil-aqueous IFT d_{text{IFT}} = e^{{ - e^{{ - X_{text{IFT}} }} }} Si (oil-aqueous IFT, mN/m) X IFT D d IFT 44.4 − 2.0 6.18 × 10−4 53.0 3.0 9.51 × 10−1.
The calculation of factor fractions (X i ) is shown in "Calculation of factor fractions (X i )" Appendix section.
Equations (4) and (5) are then used to calculate the factor fractions (X i ) for the desirable and undesirable factors, respectively.
Since the oil-aqueous IFT and fluid viscosity are desirable factors which promote the oil recovery, their factor fractions are calculated according to Eq. (4).
The oil-aqueous and aqueous-solid IFTs are desirable factors whereas the oil-solid IFT is undesirable factor, then the factor fractions (X i ) are calculated according to Eqs. (4) and (5) respectively.
