WebComparison of the boiling curves of a lubricant solution φ = 1.49% for different initial substrate temperatures: Tw0 = 140°C, Tw0 = 250°C and Tw0 = 445°C. The spray parameters are: The mean drop diameter D10 = 78.7 μ m, the mean impact velocity U = 14.05 m/s and the mass flux m = 2.50 ± 0.03 kg/m 2 s. WebFor example, the boiling point of water at sea level is 100 o C but its boiling point at an altitude of 1905 meters is 93.4 o C (since the atmospheric pressure is relatively lower at high altitudes). For a mixture of liquids, the distillation process is dependent on Dalton’s law and Raoult’s law.
