Evaporation of n-propyl alcohol into carbon dioxide for the same geome

1.	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 (‚âà√¨‚àö√ñ) = 1.8 kg/m³ , Viscosity (‚âà√≠¬¨‚à´) = 1.49‚Äö√†√∂‚àö‚â•10^-5 kg/m.s, diffusivity (DAB) = 7.6‚Äö√†√∂‚àö‚â•10^-6 m² /s and universal gas constant (R) = 8.314 J/mole.K. Estimate the Reynolds number.$
