Transient flow refers to a type of fluid flow where the velocity and pressure of the fluid change with time at any given point in the system. This kind of flow is crucial in analyzing situations where fluid properties are not constant, such as during startup or shutdown of equipment, or when there are sudden changes in operating conditions. Understanding transient flow is essential for energy analysis in unsteady-flow processes, as it affects how energy is stored, transferred, and lost in systems.
