Challenge Problems
Push your limits with advanced challenges
A rod has a thermal diffusivity of 0.05 m²/s. If one end of the rod is maintained at 100°C and the other at 20°C, calculate how long it takes for the temperature at the midpoint to reach 60°C using Fourier's Equation.
💡 Hint: Consider how distance affects time based on thermal gradients.
Suppose you are designing a heating unit that utilizes heat conduction to warm a large room efficiently. Using Fourier's Equation, determine what material properties are critical for optimal heat distribution.
💡 Hint: Analyze each parameter in relation to how heat travels in the chosen materials.
