The diametei of average mass and surface area are quantities that involve the size raised to a power, sometimes referred to as the moment, which is descriptive of the fact that the surface area is proportional to the square of the diameter, and the mass or volume of a particle is proportional to the cube of its diameter. These averages represent means as calculated from the different powers of the diameter and mathematically converted back to units of diameter by taking the root of the moment. It is not unusual for a polydispersed particle population to exhibit a diameter of average mass as being one or two orders of magnitude larger than the arithmetic mean of the diameters. In any size distribution, the relation ia equation 4 always holds. 

The equation above states that the net content in any compartment i equals the sum of all inflows from the other compartments minus the sum of all outflows towards the other compartments. Such a relation is also referred to as a mass balance differential equation, which is well-known in chemical engineering. In the... 

It follows from Equations (2.4) and (2.6) that the mass and mole fractions are related as... 

The second rule for isotopomer harmonic frequencies is the so-called Sum Rule which follows from Equation 3.A1.8. Equation 3.A1.8 relates the sum of the squares of all the frequencies to the sum of the diagonal matrix elements of the (FG) matrix diagonalized to obtain the frequencies. When mass weighted Cartesian displacement coordinates are used to calculate the vibration frequencies, this means that the sum of the A s (A = 4n2v12)can be found as follows (Equation3.51)... 

By using the latent heat of vaporization for water, Lg, from equation (8.86), the previous relations for mass transfer can also be used for heat transfer due to evaporation ... 

Returning to equation (1), it is seen that the Van Deemter equation predicts that the total resistance to mass transfer term must also be linearly related to the reciprocal of the solute diffusivity. Furthermore, it is seen from equation(l), that, if there is a significant contribution from the resistance to mass transfer in the stationary phase, the curves will show a positive intercept. 

A relation between hydrazine and oxygen mass fractions at any radial distance r is obtained from Equation 40 by integrating from rl to r. The resulting expression is... 

If it is desired to calculate the rate of mass transfer from the overall concentration-difference based on bulk-liquid compositions (x -x), the appropriate overall coefficient, Ki x, is related to the individual mass-transfer coefficients by the equation ... 

The total enthalpy flow Il of the fuel includes the enthalpy of reaction. The enthalpy flow of the incoming air is // vi. These enthalpy flows have to cover the energy output of the SOFC module which consists of the produced power Pe, the generated heat Q c and the enthalpy flow of the flue gas f l< , ]>,. From Equation (2.76) we get the respective related enthalpies h at the respective mass flows m... 

These parameters can be directly related back to the information contained in the EPM with n components (j) and m species (t). Application of the mass balance constraint equation requires that the concentration of each species must be known. Therefore, activity coefficients are computed if the ionic strength is already known from either the Davis or the extended Debye-Eluckel equation however, if ionic strength is unknown and has to be calculated, equation (5.134) can be converted to a general expression for the concentration of each species by substituting the expression for S to give... 

F = mu, relates net force to acceleration in the Xi direction. The mass of the elemental volume is given by pAxAyAz, where p is the density (mass/volume) of the solid. From Equation 2.4 and Newton s law,...
