A rectangular aluminum bar 6cm by 3cm is initially at a uniform temperature of 175 oC. Suddenly the surfaces are exposed to convective cooling by air having a heat transfer coefficient of 250W/m2 0C and a temperature of 25 0C, as shown in the figure below. Determine the centre temperature T0 of the bar 1 min after the start of cooling
