As seen in the figure, the half-free quadrilateral Rod (material: pure iron) is immersed in water at a temperature of 20 °C by the finite side (from its base), while initially at a uniform temperature of 400 °C. h = 400 W / m2K. At point A in the center of the base of the rod, how much will the temperature be after 10 minutes? (Assume that the temperature is scattered on the bar and Fo > 0.2.)
