A cylindrical-shaped product(k=0.47 W/m K, p(density)=985 kg/m^3, c_p=3100 J/kg K) 6.5 cm in diameter and 8 cm in height is taken out of the oven when it is at 75 degrees celsius and placed under ambient conditions (10 degrees celsius). Determine the center temperature of the product afer 60 minutes if the convective heat transfer coefficient between the product and mbient air is 25 W/m^2 K.
