An electric current is passed through a wire of 1 mm in diameter and 10 cm long. The wire is submerged in liquid water at atmospheric pressure, and the current is increased until the water boils. For this situation, the convection coefficient is 5000 W/ (m²K), and the water temperature will be 100°C.
How much electric power must be supplied to the wire to maintain the wire surface temperature at 114°C?
