Grashof condition calculator
WebA four-bar linkage satisfies the Grashof condition when Equation 4 is shown below; s l < p q (4) Where s, l, p, and q, all denote lengths of one of the links; in particular s is the shortest link and l is longest link. Grashof four-bar linkages can be in one of four states. Each state is identified by the action of the input and driven links ... WebThe Grashof number is defined as the ratio of the buoyant to a viscous force acting on a fluid in the velocity boundary layer. Its role in natural convection is much like that of the …
