A 75 mm long square section bar with a side length of 25 mm is initially at 220 C. The rod with a thermal diffusion coefficient of 1.17x10-5 m2 / s and a thermal conductivity of 43 W / m.K is released into an environment with a convection coefficient of 570 W / m2.K at 30 ⁰C. Since there is a temperature change over time in all 3 axes of the bar, calculate the temperature at the center of the bar after 2 minutes by using the power series solutions based on the single term approach.

Water hardening process of 2 m long and 0.05 m diameter steel bars will be carried out. The steel bar, which is heated up to 900 °C in the oven, is cooled to an average temperature of 100 °C in a water bath. The water bath is kept at a uniform temperature of 30 °C and the heat transfer coefficient between the water and the rod surface is 325 W/m2K. Accordingly, calculate the time required for the steel bar to cool to 100°C in the water bath. (Steel bar p=7832 kg/m3, cp=434 J/kgK, k=63.9 W/mK)
