A metal rod is heated at one end to a temperature of 100°C while the other remains at room temperature (20°C). If the rod has a length of 1m and thermal diffusivity of 0.1 cm²/s, determine the temperature distribution after 10 seconds.
💡 Hint: You may need to reference heat conduction equations and possibly numerical methods for transient analysis.
A wall of thickness 0.2m has a sudden change in surface temperature from 25°C to 75°C. If the thermal conductivity is 0.6 W/m·K, find the time taken for the center of the wall to reach 50°C assuming a uniform temperature change.
💡 Hint: Remember to use Fourier's law to relate how temperature varies with thickness.
