Unformatted text preview: (k=237 W/m K). The fin heat transfer coefficient is h = 35 W/m 2 K and the air temperature is 30 C. The fins are arranged in a square pattern, 0.6 cm on centers, 15 fins to a row. What is the total heat loss from the fins assuming a. an infinite fin and b. a finite fin insulated on the end? 4. A cylindrical, pin fin has a base temperature of 175 C and is surrounded by air at 25 C with a convection coefficient h = 30 W/m 2 K. The fin has a length of 75 mm, a diameter of 5 mm and is made of brass. Assuming a finite fin with an insulated end, determine the following: a. The heat transfer from the fin, b. The fin temperature at L/2, c. The fin efficiency....
