WebGrashof's theorem states that a four-bar mechanism has at least one revolving link if s + l = p + q (5-1) and all three mobile links will rock if s + l > p + q (5-2) The inequality 5-1 is … 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
