Water in the bottom of a narrow metal tube is held at a constant temperature of 293 K. The total pressure of air (assumed dry) is 1.01325 x 10³ Pa (1 atm) and the temperature is 293 K. Water evaporates and diffuses through the air in the tube, and the diffusion path z2-z₁ is 0.1524 m long. The diffusivity of water vapor at 293 K and 1 atm pressure is 0.250 x 104 m²/s. Calculate the rate of evaporation at steady state in kg mol/s.m². Assume that the system is isothermal.
