Two finned surfaces with long fins are identical, except that the con...
∵ For fim 
the heat transfer coefficient is twice that of fin 
so the effectiveness and efficiency both will be lower for fin 
as compare to fin 
the heat transfer coefficient is twice that of fin so the effectiveness and efficiency both will be lower for fin as compare to fin Most Upvoted Answer

Statement:
The convection heat transfer coefficient for the first finned surface is twice that of the second one.
Explanation:
To understand the efficiency and effectiveness of the finned surfaces, we need to consider their heat transfer performance.
Efficiency:
Efficiency is a measure of how well a system converts input energy into useful output energy. In the case of finned surfaces, efficiency refers to how effectively the fins transfer heat from the surface to the surrounding fluid.
Effectiveness:
Effectiveness is a measure of how well a system achieves its intended purpose. In the case of finned surfaces, effectiveness refers to how well the fins enhance heat transfer from the surface to the surrounding fluid.
Comparison:
Let's compare the first finned surface (with a higher convection heat transfer coefficient) to the second finned surface (with a lower convection heat transfer coefficient).
Efficiency:
The efficiency of a finned surface depends on the rate of heat transfer from the surface to the fluid. A higher convection heat transfer coefficient implies a higher rate of heat transfer. Therefore, the first finned surface with a higher convection heat transfer coefficient will have a higher efficiency compared to the second finned surface.
Effectiveness:
The effectiveness of a finned surface depends on how well the fins enhance heat transfer. While a higher convection heat transfer coefficient leads to higher efficiency, it does not necessarily imply better fin performance. The effectiveness of the fins is influenced by factors such as fin geometry, spacing, and material properties. Therefore, the first finned surface with a higher convection heat transfer coefficient may not necessarily have a higher effectiveness compared to the second finned surface.
Conclusion:
Based on the above analysis, we can conclude that the first finned surface (with a higher convection heat transfer coefficient) will have a higher efficiency but may not have a higher effectiveness compared to the second finned surface. Therefore, the accurate statement for the efficiency and effectiveness of the first finned surface relative to the second one is option 'D': Lower efficiency and lower effectiveness.
