1 determine the heat transfer rate of 100 fins a plane wall 1m x 1m ha
A plane wall (1m x 1m) has 100 infinitely long fins (k = 200 W/m-K) of rectangular profile. The fins are 0.5 mm thick and equally spaced at a distance of 1 cm (100 fins/m). The fins are exposed to cold air (h= 30 W/m²K) and the temperature difference between the wall and the cold air is 100°C. 1. Determine the heat transfer rate of 100 fins. 2. Determine the total heat transfer rate of the entire system including 100 fins and base walls between the fins.
