One end of the long rod 35mm in diameter, is inserted into a furnace with the other end projecting in the outside air having heat transfer coefficient of 65 W/m²°C and temperature 25°C and thermal conductivity of the fin material is 51.2W/m°C, the effectiveness of the fin was found that 9.5. If the heat transfer coefficient of the air to which the fin is exposed is reduced to 25W/m²°C, then the effectiveness of the fin is (a) 24.7 01 (b) 13.6 (c) 15.32 (d) 234 One end of the long rod 35mm in diameter, is inserted into a furnace with the other end projecting in the outside air having heat transfer coefficient of 65 W/m²°C and temperature 25°C and thermal conductivity of the fin material is 51.2W/m°C, the effectiveness of the fin was found that 9.5.
