Repeat Prob. 5162 for a copper wire ( = 8950 kg/m3 and c p = 0.383 kJ/kg

Repeat Prob. 5–162 for a copper wire (ρ = 8950 kg/m3 and c_p = 0.383 kJ/kg · °C).

Data From Q# 162:

Long aluminum wires of diameter 5 mm (ρ = 2702 kg/m3 and c_p = 0.896 kJ/kg · °C) are extruded at a temperature of 350°C and are cooled to 50°C in atmospheric air at 25°C. If the wire is extruded at a velocity of 8 m/min, determine the rate of heat transfer from the wire to the extrusion room.
