Challenge Problems
Push your limits with advanced challenges
A pin fin with an insulated tip is 0.5 m long and has a diameter of 0.01 m. If the thermal conductivity is 200 W/m·K and the convection coefficient is 25 W/m²·K, calculate its maximum heat transfer efficiency.
💡 Hint: You need to determine the total heat transfer based on the parameters given.
If a pin fin cools a component from 100°C to 50°C over a period, and you know the heat transfer at the tip, how would you find the efficiency of the pin fin?
💡 Hint: Evaluate how much energy is actually passing through versus what could ideally pass through.
