(theoretical liquid holdup at the flooding point) is given by the equation:

It is easy to see that the last three equations are not dimensionless
either.
The values of CFI for different random packings are presented in Table
10.
For calculating the maximum efficient capacity factor which determines
the value of the gas velocity at maximal mass transfer efficiency of the column
for the packing IMTP, Rukovena and Koshy [291] presented figure IS. Here the
value of Co for packings with different dimensions is presented as a function of
the flow parameter
