An aluminum fin 1.6 mm thick surrounds a tube 2.5 cm in diameter. The length
of the fin is 12.5 mm. The tube-wall temperature is 200◦C, and the environment
temperature is 20◦C. The heat-transfer coefficient is 60 W/m2 · ◦C. Consider the heat dissipated in a pipe 1.20 m long if the fins are 4.2 mm apart from center to center

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
