Electric current is passed through a 2-mm diameter cylindrical metal rod with emissivity of 0.5. The rod is submerged horizontally in water under atmospheric pressure and the rod surface temperature reaches 500°C. Determine the boiling heat transfer coefficient and the total heat transfer coefficient.
