• Evaporation of n-propyl alcohol into carbon dioxide for the same geometrical arrangement of tube diameter (d) of 38 mm when the carbon dioxide flows at a maximum velocity (ug) of 10 m/s at 300 K and 1 atm. Properties of dilute mixtures of propyl alcohol in carbon dioxide at 300 K and 1 atm are: Molecular weight (M) = 44 gm/mole, density (ρ) = 1.8 kg/m3 , Viscosity (μ) = 1.49×10-5 kg/m.s, diffusivity (DAB) = 7.6×10-6 m2 /s and universal gas constant (R) = 8.314 J/mole.K. Estimate the Reynolds number. Nu = 0.453Re0.568 Pr0.36, where 10 < Re (= ρug d/μ)<106 and 0.7 < Pr < 500
