Consider two very long, straight fins of uniform cross section, as shown in Figure 3.17. The rectangular fin has dimensions t = 1 mm and w = 20 mm. The circular pin fin has the same cross-sectional area as the rectangular fin. Both fins are constructed of aluminum with k = 237 W/m ∙ K.

A pin fin of uniform, cross-sectional area is fabricated of an aluminum alloy (160 W/m-K). The fin diameter is D=7 mm, and the fin is exposed to convective conditions characterized by 220 W/m²K. It is reported that the fin efficiency is 7, 0.55. Determine (a) the fin length & and the fin effectiveness ry. Account

In a diode, what is the depletion zone and why is it given that name? The Correct Answer and Explanation is : A depletion zone in a diode is a region near the junction between the p-type and n-type materials where mobile charge carriers (electrons and holes) are depleted, leaving behind immobile ionized donor and
