Question:
In boiling water at 1 atm pressure outside a stainless-steel tube with a surface temperature of 410°F, the heat-transfer coefficient h in the absence of radiation is 32 Btu/h·ft2·°F. If the emissivity of the stainless steel is 0.8, will radiation significantly augment the rate of boiling (i.e., by more than 5 percent)? Assume that vapor film is transparent to radiation and the boiling liquid is opaque.
