The correlation of critical heat flux (CHF) is derived for thin horizontal wires on the basis of the relation, q_<CHF>=δ_1ρ_1H_<fg>f. This relation was derived from the model, in which liquid film on the surface of wires is just dryout when coalesced bubbles depart from the surface. The correlations of δ_1 and f are given in the third and forth papers of this series, respectively. The macrolayer correlation on flat surfaces is modified for very thin wires by taking into account of the effect caused by the thin diameter of heated wires. Calculations of CHF are made as a parameter of wire diameter for various liquids. The calculted results are compared with the values measured by Sun et al. and the present authors, and the excellent agreement between them are obtained.
