👉 A finite fluid refers to a substance whose volume and pressure are constrained by physical boundaries or conditions, such as the walls of a container or specific temperature and pressure limits. Unlike an infinite fluid, which can expand or contract without bound, a finite fluid has a defined size and cannot expand to fill any void. This concept is crucial in various fields, including physics, engineering, and chemistry, where understanding the behavior of fluids within confined spaces is essential for accurate modeling and practical applications.
