Repeat Problem 23.29 for the case when the liquid residence time is 5 min instead of 10 min for Examples 23.4, 23.5, and 23.6. You may assume that the heights of liquid in the drum are the same.

Problem 23.29

Consider the horizontal V-L drum designed in Examples 23.4, 23.5, and 23.6. Based on the conditions at the operating design point (using NOL), determine the maximum size of gas bubble that would not rise to the liquid surface and be released to the vapor phase. Use a liquid viscosity of 700 × 10 kg/m/s.

Consider a horizontal drum used to separate a V-L mixture. The HHAL of the liquid is set at 0.8 Dves and the vapor and liquid properties are: P₁ = 1000 kg/m³, pg = 2.156 kg/m³, µg = 19.62 × 10 kg/m/s, vg = 3.865 m³/s. Determine the diameter of the drum, Dues.
