The base of the fin is typically set to a constant reference temperature, . There are four commonly possible fin tip () conditions, however: the tip can be exposed to convective heat transfer, insulated, held at a constant temperature, or so far away from the base as to reach the ambient temperature. For the first case, the second boundary condition is that there is free convection at the tip. Ther… Webwhere is an internal temperature. These two quantities must be of the same magnitude. If , then .In other words, if , there is a much larger capability for heat transfer per unit area across the fin than there is between the fin and the fluid, and thus little variation in temperature inside the fin in the transverse direction.To emphasize the point, consider …

WebFactors affecting fin effectiveness. P.Kh.Ac should be greater than unity if the rate of heat transfer from the primary surface is to be improved. If the ratio of P and Ac is increased , … WebThe first is fin effectiveness. ... The fin efficiency will always be less than one, as assuming the temperature throughout the fin is at the base temperature would increase the heat transfer rate. The third way fin performance … highbox w3

WebFin effectiveness \\textbf{Fin effectiveness} Fin effectiveness is the ratio of heat transfer rate from a finned surface to the heat transfer rate from the same surface if there were no fins, and its value should be greater than 1 1 1. And is defined in the following expression: WebFeb 20, 2014 · 3 Answers. A) Gamma < 1 means attractive forces dominate, and there is a decrease of vapour pressure of solute A relative to pure A. B) Gamma > 1 means repulsive forces dominate, and there is an increase of vapour pressure of solute A relative to pure A. You can think of activity coefficients as a qualifier for "escaping tendency" of the solute. highburystaffhub
