Along wire of diameter 1 mm is submerged in an oil bath of temperature β 31Β°c. the wire has an electrical resistance per unit length of 0.01 Ο/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2Β·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1Β°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kgΒ·k, and 20 w/mΒ·k.
