LTR: Fluid Drag
LTR: Fluid drag Not surprisingly, as a Fluid flows past a solid object it exerts a force on the solid. There are severalclasses of force typically discussed in Fluid mechanics, but the two most common are drag and :The drag force is the component of the force from the Fluid on the solid that is in the directionparallel to the flow (here denoted as the x direction).DEFINITION:The lift force is the component of the force from the Fluid on the solid that is in the directionperpendicular to the flow (here denoted as the y direction).In both the case of drag and lift the forces arise from two sources: Fluid friction (viscousforces), and non-uniform pressure distributions (pressure forces).NOTE:Lift forces are only very weakly dependent on friction .
