Question: A horizontal 1-mm-diameter stainless-steel wire having k = 16 W/m oC and a resistivity of 70 cm is exposed to air at 1 atm

A horizontal 1-mm-diameter stainless-steel wire having k = 16 W/m· oC and a resistivity of 70 μΩ· cm is exposed to air at 1 atm and 20oC. The wire length is 1 m. What is the maximum temperature that will occur in the wire and the voltage that must be impressed on it to produce a surface temperature of 134oC?
