Triangular fins are attractive because they require less mass than straight fins with comparable power dissipation. The figure on the right describes such a fin. The tapered wall is defined with the function y=ax and the width of the taper b>>aL, where L is the fin's length. The base temperature is TH. 2.1 (5%) State the equation and boundary conditions for the fin's cross-section averaged temperature. 2.2 (5%) Recast the fin equation of (A) into the dimensionless form
