Challenge Problems
Push your limits with advanced challenges
A circular duct has an internal diameter of 0.1 m and an air flow rate that results in a Reynolds number of 3200. Calculate the Nusselt number assuming turbulent flow with a constant wall temperature.
💡 Hint: Make sure to understand how the Prandtl number affects the results.
For a heat exchanger experiencing forced convection, the wall temperature is 75°C and the bulk temperature of the fluid entering is 25°C. Given the heat transfer coefficient of 50 W/m²·K, calculate the heat transfer rate for a surface area of 2 m².
💡 Hint: Remember to calculate ΔT correctly.
