WebExpert Answer. 14.9. In boiling water at 1 atm pressure outside a stainless-steel tube with a surface tenm- perature of 410°F, the heat-transfer coefficient h in the absence of radiation is 32 Btu/h ft?. °F. If the emissivity of the stainless steel is 0.8, will radiation signif- cantly augment the rate of boiling (i.e., by more than 5 percent)?
