3.) Consider a long 0.8-mm-diameter aluminium wire (originally at 25C) immersed in an oil bath that is at 25C. The wire has an electrical resistance per unit length of = 0.0572 /. If an electric current of 100 A is flowing through the wire and the convection coefficient between the wire and oil bath is 550 W/m2 K determine, a) the steady state temperature of the wire at its centerline (in C) b) how long it takes to reach the steady state temperature (in seconds) c) how long it takes for the outer surface of the wire to reach T= 300 C (in seconds)
