Which of the following statements are correct when considering fin performance? 1. Fins should be very long to increase efficiency 2. Thin fins have a higher effectiveness than fat fins 3. Fins should be close together. 4. Fat fins have a higher effectiveness than thin fins 5. Heat transfer coefficient in the gaps between fins should be considered when deciding on fin placement. 6. Thermal resistance at the base of the fin should be minimised to improve performance. ☐7. Fins have a more significant impact on heat transfer when they are in an area with low heat transfer coefficient than when they are in an area with high heat transfer coefficient. 8. Manufacturing the base and the fin from a single piece of material is preferable to adding thin fins to the base separately. 9. Thermal resistance at the base of the fin should be maximised to improve performance. 10. Fins should be spaced far apart.
