The temperature of the mixture of steam and droplets will be *at* the boiling point. The actual boiling point inside the conduit will be slightly elevated because of a slight increase in pressure. Rossi emphasizes that the pressure is at atmosphere inside the reactor, but in fact it must be slightly higher, or there would be no flow of the fluid. The pressure difference, flow rate, and tube geometry are related by a simple formula, and reasonable estimates indicate an elevation in the bp of a degree or so is easily plausible.
