Pressure drop and Hold-up of Perforated Plate Column
The hold-up on the plate and the pressure drop through the plate under various conditions were measured, and it was found that the hold-up was not constant for either the rates of liquid or those of vapor. On the basis of this experimental results the mechanism of pressure-drop through the perforate...

| Abstract | The hold-up on the plate and the pressure drop through the plate under various conditions were measured, and it was found that the hold-up was not constant for either the rates of liquid or those of vapor. On the basis of this experimental results the mechanism of pressure-drop through the perforated plate was discussed and the following results wer obtained; 1) The amount of hold-up increases with the increase of the overflow rate and decreases with the increase of the gas or vapor rate. 2) The relation between Δpw and H is given by the equation 3) The foaming density is shown by the following equation. 4) The pressure drop through the dry plate is shown by the equation Although the coefficient of discharge, c, varies with the changes of the diameter of the bole and the thickness of the plate, it is independent of the pitch of the hole. 5) The total pressure drop through the plate is given by the following equation. |
