Challenge Problems

Push your limits with challenges.

Question 1

You have a heated vertical plate at 100 Β°C in a room where the temperature is 25 Β°C. Calculate the Grashof number if the height of the plate is 2 m and assess if free convection occurs.

πŸ’‘ Hint: Identify physical properties of air at the operational temperature.

Question 2

A cylindrical exterior surface is subjected to a turbulent flow of water. If Re = 500, calculate Nusselt number using the applicable correlation and find heat transfer coefficient.

πŸ’‘ Hint: Be sure to convert the Nusselt number to actual values after calculation.
