Sizing is based on keeping fluid velocity at or below the selected design limit (4 ft/sec is standard to allow effective air and dirt separation without excessive pressure drop or erosion). This is a preliminary sizing tool; always confirm against the manufacturer's published flow/pressure-drop chart for the specific separator model, especially for coalescing media or magnetic separator types where flow capacity may differ from a simple velocity calculation.
