Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A blackbody at 500 K emits energy. Calculate its emissive power using the Stefan-Boltzmann Law. Then, compare to a grey surface with an emissivity of 0.8 at the same temperature.

💡 Hint: Use provided constants and apply the right formulas.

Challenge 2 Hard

Analyze a situation in a furnace with two surfaces: Surface A with T1=800 K and ε1=0.9; Surface B with T2=400 K and ε2=0.2. Calculate the heat transfer using q12 formula.

💡 Hint: Be careful with the values used in the q12 equation.
