A voltage difference of 50 volts is imposed on a 4.5 m long, 4.0 mm diameter stainless steel wire (k=15.2 W/m-K). The electrical resistivity of stain- less steel at these conditions is 0.72 x 10 ohm-m. The wire is uninsulated and submerged in water at 25C with a convection coefficient of 750 W/m2-K. (a) What is the rate of heat transfer from the wire? (b) What is the surface temperature of the wire? (c) What is the center temperature of the wire
