The surface of a horizontal, 7-mm-diameter cylinder is maintained at an excess temperature of 5C in saturated water at 1 atm. Estimate the heat flux using an appropriate free convection correlation and compare your result to the boiling curve of Figure 10.4. Repeat the calculation for a horizontal, 7-m-diameter wire at the same excess temperature. What can you say about the general applicability of Figure 10.4 to all situations involving boiling of water at 1 atm?
