The values of Cp for different packings with different dimensions are
given in Table 6.
3.2.1.2.1.3. Liquidholtfap
3.2.1.2.1,3.1. Liquid holdup under the loading point
For determination of the static liquid holdup (H s) Shulman et al. [42,
43] proposed the equation;

d P2 is the diameter of a sphere with a surface area equal to the surface area of the
packing element in m;
fi L - liquid dynamic viscosity in mPa.s;
O" - surface tension in mN/m;
The diameter d p% is:
