A plane wall with surface temperature of 300°C is .attached with straight aluminum triangular fins (k = 236 W/m·K). The fins are exposed to an ambient air condi- tion of 25°C and the convection heat transfer coefficient is 25 W/m2·K. Each fin has a length of 55 mm, a base of 4 mm thick and a width of 110 mm. Using Table 3–4, determine the efficiency, heat transfer rate, and effectiveness of each fin.
