Grashof's rule
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 WebUse the cosine rule to determine the stroke length (total angular motion) of the rocker. 31.36 80 47.5 76 14 12 Problems related to the oil pump mechanisms a.
