WebGRASHOF’S THEOREM Grashof’s theorem [7] was first introduced in 1883 to deal with the mobility problem of planar four-bar mechanisms, in particular, mechanisms with all … WebThe Grashof theorem provides the basic condition that the four-bar linkage must satisfy so that at least one link completes a full revolution. According to this theorem, a four-bar linkage contains one or more crank links if the combined length of the shortest and longest links does not exceed the combined length of the two remaining links.

This method takes into account the buoyancy force per unit volume, F b {\displaystyle F_{b}} due to the density difference in the boundary layer and the bulk fluid. See more 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 See more The Rayleigh number, shown below, is a dimensionless number that characterizes convection problems in heat transfer. A critical value exists for the Rayleigh number, … See more In a recent research carried out on the effects of Grashof number on the flow of different fluids driven by convection over various surfaces. … See more Heat transfer Free convection is caused by a change in density of a fluid due to a temperature change or gradient. Usually the density decreases due to an increase in temperature and causes the fluid to rise. This motion is … See more The first step to deriving the Grashof number is manipulating the volume expansion coefficient, $${\displaystyle \mathrm {\beta } }$$ as follows.
