WebA pipe of radius Ro has a circular fin of radius R1 and thickness 2B on it (as shown in the figure below). The outside wall temperature of the pipe is Tw and the ambient air temperature is Ta. Neglect the heat loss from the edge of the fin (of thickness 2B). WebA circular fin on a pipe with outside wall temperature To is with a very small thickness of dimension B so that heat transfer through its edge at R, is negligible. The circular-disk like fin is the extended area which is used for a heat loss through the convection effect when the goal is to maintain certain temperature within the pipe. how a short sale works for the buyer
