Grashof condition calculator

WebThe ratio of the Grashof number to the square of the Reynolds number may be used to determine if forced or free convection may be neglected for a system, or if there's a combination of the two.This characteristic ratio is known as the Richardson number (Ri).If the ratio is much less than one, then free convection may be ignored. WebIf l + s > p + q (if the sum of the longest and the shortest link lengths is greater than the sum of the lengths of the two intermediate links).; Only double-rocker mechanisms are possible (four different mechanisms, depending on the fixed link). If l + s = p + q the four possible mechanisms in (1) will result.However these mechanisms will suffer from a condition …
