👉 The run fluid, also known as the main flow or bulk flow, is a critical component in fluid dynamics that describes the movement of a continuous fluid through a system or pipe without significant changes in its cross-sectional area. It represents the overall velocity and volume of fluid flow, essential for understanding how fluids behave in various engineering applications such as pipelines, hydraulic systems, and aerodynamics. The run fluid's characteristics, including its velocity profile and turbulence, are crucial for predicting pressure drops, heat transfer rates, and overall system efficiency.
