A stainless steel bar is initially at a temperature of 25C. Its upper surface is suddenly exposed

Question:

A stainless steel bar is initially at a temperature of 25°C. Its upper surface is suddenly exposed to an air stream at 200°C, with a corresponding convective coefficient of 22 W/m2 · K. If the bar is considered semi-infinite, how long will it take for the temperature at a distance of 50 mm from the surface to reach 100°C?
