Freeman-Watts procedure

The Freeman-Watts procedure is an engineering method used to analyze the flow of fluids, like liquids or gases, through porous materials such as filters or rock layers. It helps determine how the fluid moves by measuring pressure differences at different points and calculating properties like permeability. Essentially, it provides a way to predict and understand flow behavior within porous structures, which is important in fields like petroleum engineering, hydrology, and environmental engineering. The procedure uses specific equations to relate observed pressure drops to flow rates, aiding in the design and evaluation of systems involving fluid movement through porous media.
