Grashof's criterion
WebGrashof Number. The Grashof number is defined as (8.54)Gr=gβΔTz3ν3where β is the air expansion coefficient, ΔT is the temperature difference, and z is the length of the path followed by the airstream generated by ΔT.

WebJan 12, 2024 · A 4 revolute pair chain is called the Grashof chain if the following condition is satisfied: l + s . p + q (Class-I four-bar linkage) i.e. the sum of the shortest and longest link should not be greater than the other two. If a Grashof chain with 4 revolute pairs is considered then the following three distinct inversions are possible. Double crank:
