QUESTION 2 [15 MARKS] Water in the bottom of a narrow metal tube is held at constant temperature of 233 K. The total pressure of air (Assumed dry) I 1.21325*105 Pa and the temperature is 233 K. Water evaporates and diffuses through the air in the tube and the diffusion path z2 - Z₁ is 0.25 m long. Calculate the rate of vaporisation at steady state in kg mol/s.m². The diffusivity of the water vapor at 233 K 0.250*10-4 m²/s. Assume the system is isothermal. Where the vapor pressure of water at 330K is 5.35*10³ Pa. [15]
