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 (u_g) 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 ( ) = 1.8 kg/m³ , Viscosity ( ) = 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 = 0.453R_e^0.568 P_r^0.36, where 10 < R_e (= u_g d/ )<10⁶ and 0.7 < P_r < 500
