A characteristic feature of the hydrolysis of esters and of most other organic compounds is that a third substance, ordinarily an acid or a base, increases the rate at which the chemical change takes place. As pointed out in this article, twophase heat transfer coefficients can be quantitatively expressed in terms of three regions which are termed strati- `fied, slug and annular roughly in order of increasing proportions of gas to liquid. Federal government websites often end in .gov or .mil. Figure 5.4. Substantially all of the fatty acids were in the vapor phase. With vertical orientation, with the gas and liquid streams moving downwardly, the gas may travel at a lower absolute velocity than the liquid because of the buoyant effect of the gas. Exercise intensity and duration are important determinants of fat oxidation. Epub 2023 Feb 1. The slug flow condition can be characterized as one in which the liquid component or phase moves in large slugs alternately with slugs of gas. Fats are soluble in organic solvents and insoluble in water. Triglycerides present in fats can be hydrolyzed in the presence of a base, an acid, or lipases. 5. These terms are delined in my article entitled, Heat Transfer and Pressure Drop in Two-Phase Flow, published in the Chem.
