If there is a solute a dissolved in the water at an initial concentration of 0.1 mol/m3. the water in the cylinder is being stirred at 100 rpm. assume negligible concentration of a in ambient air. viscosity of water: 1 x 10-3 kg/m-s density of water: 1000 kg/m3 diffusion coefficient of a in water: 4 x 10-10 m2/s diffusion coefficient of a in air: 3.4 x 10-6 m2/s for the water side mass transfer coefficient, assume the following correlation nsh 0.879 (n re)0.5 (nsc)0.33 estimate the reynolds number converting the rpm to linear velocity through angular velocity. estimate the water-side mass transfer coefficient in (m/s) estimate the overall mass transfer coefficient in (m/s) estimate the flux of a in g/m2-day. i. ii iv if the water is stagnant, what is the flux of a? will there be an influence of the air velocity on the flux of a? will there be an influence of the evaporation of water on the v vi. vii evaporative flux of a?
