👉 The short fluid, also known as the short vapor or short-term vapor pressure, refers to the partial pressure of a volatile component in a liquid at a given temperature when the liquid is in equilibrium with its vapor phase. It is typically lower than the bulk vapor pressure, which represents the total pressure exerted by all vapor molecules in the liquid. The short fluid is crucial in understanding the behavior of liquids under various conditions, such as distillation processes, where it helps in separating components based on their volatility.
