= = O O A semi - infinite aluminium cylinder (k = 237 W/mK, a 9.71 x 10 m / s) of diameter 20 cm is initially at a uniform temperature of 200°C. The cylinder is now placed in water at 15°C where heat transfer takes place by convection with h = 120 W/m2 K. Determine the temperature at the centre of the cylinder 15 cm from the end surface 5 min after the start of the cooling. =
