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 revolute joints. Consider a four-link kinematic chain, let s be the shortest link length, l be the longest link length, p and q be the link lengths of the remaining two ... Buckingham π theorem Another form of dimensional analysis that will result in the Grashof number is known as the Buckingham π theorem . 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 first step to deriving the Grashof number is manipulating the volume expansion coefficient, $${\displaystyle \mathrm {\beta } }$$ as follows. The $${\displaystyle v}$$ in the equation above, which represents specific volume, is not the same as the See more • Cengel, Yunus A. (2003). Heat and Mass Transfer: A Practical Approach (3rd ed.).
