A long wire of diameter D = 1 mm is submerged in an oil bath of temperature T = 25°C. The wire has an electrical resistance per unit length of R = 0.01 /m. If a current of I= 100 A flows through the wire and the convection coefficient is h = 500 W/m². 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 1°C of the steady- state value? The properties of the wire are p = 8000 kg/m³, c = 500 J/kg K, and k = 20 W/m K. ● ●

Question
![A long wire of diameter D = 1 mm is submerged in an
oil bath of temperature T = 25°C. The wire has an
electrical resistance per unit length of R = 0.01 2/m.
If a current of I = 100 A flows through the wire and the
convection coefficient is h = 500 W/m².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 1°C of the steady-
state value? The properties of the wire are p =
8000 kg/m³, c = 500 J/kg K, and k = 20 W/m.K.
