WebAnnular fin. The temperature distribution within the annular fin is given by the differential equation. (9.32) where h is the heat transfer coefficient between the air and the surface of the annular fin, λ is the thermal conductivity of the fin, and T∞ is the temperature of air far away from the fin. WebFeb 1, 2003 · and k fin is the thermal conductivity of the fins. Using these equations it is possible to estimate heat sink thermal performance in terms of the thermal resistance from the temperature at the base of the fins to the temperature of the air entering the fin passages. It may be noted that the relationship for Nusselt number (8) includes the ... WebFin Convection Experiment . ... done in the conductivity experiment. The knob on each fin allows different power input to be achieved in each heater. The switchbox can be used to set the voltage and current ...
