WebThe role played by Reynolds number in forced convection is played by the Grashof number in natural convection. The critical Grashof number is observed to be about 109 for vertical plates. Thus, the flow regime on a vertical plate becomes turbulent at Grashof number greater than 109. The heat transfer rate in natural convection is expressed by WebDec 15, 2005 · F. Grashof classified four bar mechanisms into three types (double-cranks, rocker cranks, and double-rockers) and gave a set of rules for identifying the different types.
WebGrashof's Law. When designing a linkage where the input linkage is continuously rotated e.g. driven by a motor it is important that the input link can freely rotate through complete revolutions. The arrangement would not work if the linkage locks at any point. For the four bar linkage Grashof's law provides a simple test for this condition
The crank–rocker mechanism is, basically, a four-bar mechanism in which the output link oscillates when the input link completely rotates, consistent with Grashof’s Law.
