Figure 4.18 may be used to calculate the liquid flowrate which would cause the column to flood. At a value of the ordinate of 0.048, the flooding line gives ... 

The correlation of Eckert (Fig. 13.37) combines a pressure drop relation and safe flow rates insofar as staying away from the flooding point is concerned. A flooding line corresponds to pressure drops in excess of 2 in. water/ft. In use, a pressure drop is selected, and the correlation is applied to find the corresponding mass velocity G from which the tower diameter then is calculated. Another correlation recommended by a manufacturer of packings appears in Figure 13.40. Example 13.16 compares these correlations for a specific case they do not compare any more closely than could be expected from the scatter of flooding data. 

Line FGHC is the flooding line which can be defined by either of the following criteria ... 

Point G is the intersection of the flooding line with the zero fluid velocity axis u 0 = 0, and thus marks the maximum particles throughput for continuous sedimentation. 

Note that the molecular weights of water and air are 18 and 29 Ib/lbmol, respectively. The value of the ordinate at the flooding line is determined from Figure 24 ... 

Generalized correlations for Rood point prediction have been based ou the early wort of Sherwood et aL19 Modifications of this wort have been made from time to time, with that of Eckert,20 mentioned eartier in connection with pressure drop estimation, being representative of those now in tise. The flood line is designated as the top curve of Fig. 5-8-12. Thus, as for pressure drop, the Eckert chart enables a quick estimate of the maximum allowable vapor flow through the packed bed in question.

A significant character of the flooding line lies in that, in its range of gas velocity (between C and B) and for solids-downward flows (Gs<0), there may coexist two states at one specific gas velocity. That is, two e coexist for a given set of Ug and Gj. In contrast, in the area of concurrent-up flow (to the right of the classical fluidization), there is only one state for any given set of... 

Science cannot be abandoned in engineering institutions for the sake of practicality and applications. Not the engineering subjects only but at early classes the science history and philosophy must be explained at least along flood lines or between the sentences, so that the students will know what they are dealing with and how science and technological developments took place throughout the...
