In fluid mechanics (especially fluid thermodynamics), the Grashof number (Gr, after Franz Grashof ) is a dimensionless number which approximates the ratio of the buoyancy to viscous forces acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number (Re). WebThe Law of Grashof establishes that: In a flat four - bar mechanism articulated with one fixed, at least one of the bars can make a full turn, provided longer the sum of the shortest bar and the bar is less than or equal to the sum of the other two.. There are five flat four-bar or link mechanisms that comply with Grashof's law (An example is shown in Figure 1).
