Challenge Problems
Push your limits with challenges.
Question 1
Calculate the heat transfer rate for a surface with a thermal conductivity of 0.6 W/m.K, density of 950 kg/m³, dynamic viscosity of 0.001 Pa.s, and temperature difference of 10°C. Use Nusselt's equation.
💡 Hint: Ensure all units match and align with the equation sections.
Question 2
If the film thickness doubles, what effect would it have on the heat transfer rate? Provide reasoning based on thermal resistance principles.
💡 Hint: Think of how insulation works: more thickness, less transfer.
