WebNov 5, 2012 · Grashof's law [1] states that the sum of the longest and the shortest link must be less than or equal to the sum of the remaining two links. This condition must be met to allow at least one link to make a complete revolution. The four-bar linkage of this Demonstration has four joints () and a total of four links ( ), of which one is grounded ( ).

WebNusselt number. In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but ... The Grashof number is: G r L = g β ( T s − T ∞ ) L 3 ν 2 {\displaystyle \mathrm {Gr} _ {L}= {\frac {g\beta (T_ {s}-T_ {\infty })L^ {3}} {\nu ^ {2}}}\,} for vertical flat plates. G r D = g β ( T s − T ∞ ) D 3 ν 2 {\displaystyle \mathrm {Gr} _ {D}= {\frac {g\beta (T_ {s}-T_ {\infty })D^ {3}} {\nu ^ {2}}}\,} for pipes.
