Repeat Prob. 6-163 for a copper wire (ρ = 8950 kg/m3 and cp = 0.383 kJ/kg · °C).

Prob. 6-163.

Long aluminum wires of diameter 3 mm (ρ = 2702 kg/m3 and cp = 0.896 kJ/kg · °C) are extruded at a temperature of 350°C and are cooled to 50°C in atmospheric air at 30°C. If the wire is extruded at a velocity of 10 m/min, determine the rate of heat transfer from the wire to the extrusion room.
