A short iron cylinder ( k = 60W / m K , a = 1.6
x 103 m² / s ) of diameter 5 cm and height 4 cm is initially at a
uniform temperature of 225 ° C . Suddenly the boundary surfaces are
exposed to an ambient fluid at 25 ° C with a heat transfer
coefficient of 500 W / m² K. Calculate the centre temperature at 2
min after the start of cooling
