WebDec 1, 1986 · Five-Bar Grashof Criteria. J. Mech., Trans., and Automation. Dec 1986, 108 (4): 533-537 (5 pages) In this paper, the five-bar Grashof criterion is proposed and proved. A five-bar linkage is a Class I linkage if l max + l min 1 + l min 1 ≤ m + n is satisfied, otherwise it is a Class II linkage. Depending on the location of the two input links ... WebThe Grashof ( Gr) number gives the ratio of buoyant forces to viscous forces and is used to determine the flow regime of fluid boundary layers in laminar systems. The Gr number is defined for a compressible fluid as: (8.23) or (8.24) where LC is the characteristic length that is frequently chosen as the vertical distance where buoyancy occurs.
