Using Hunt s equation, prove that the ratio of concentration at 0.08 Z7/from the top is the concentration at pipe center expressed by... 

A tower diameter is selected based on Souders-Brown (20-50 percent conservative, usually) or Hunt s relation, Equation 8-250. 

Note that the lubrication effect due to particle collisions in liquid is significant. The liquid layer dynamics pertaining to the lubrication effect was examined by Zenit and Hunt (1999). Zhang et al. (1999) used a Lattice-Boltzmann (LB) simulation to account for a close-range particle collision effect and developed a correction factor for the drag force for close-range collisions, or the lubrication effect. Such a term has been incorporated in a 2-D simulation based on the VOF method (Li et al., 1999). Equation (36) does not consider the lubrication effect. Clearly, this is a crude assumption. However, in the three-phase flow simulation, this study is intended to simulate only the dilute solids suspension condition (ep = 0.42-3.4%) with the bubble flow time of less than 1 s starting when bubbles are introduced to the solids suspension at a prescribed ep. 

Hanson and Larson used the equation of Hunt to determine runup heights in the southern Baltic Sea for the period 1982-2004, from which the runup levels were derived by taking into account the water levels. Empiric distribution functions were then fitted to the data to extrapolate the total water level (runup level) to high return periods. Figure 38.9 illustrates the empiric distribution function for the annual maximum runup level plotted with Gringorten s formula together with a fitted Gumbel distribution. 

Outside the primary sphere is one in which the molecules are somewhat polarized, but not intensely so. If we take the radius of the ion r to be the radius of the primary sphere, we may follow Bom (1920) and Hunt (1963) and calculate the free energy of transfer of an ion of radius r from one medium to another (let us assume that one is water and the other a solvent S) according to Equation 2.24, or for a mole of a 1 1 electrolyte. Equation 2.25 ...
