3. Pure water at 20°C and velocity of 1 m/s is flowing tube with inside wall coated with benzoic acid. The tube is 2 m long with an inside diameter of 0.01 m. The solubility of benzoic acid in water is 30 gmol/m³, and the diffusivity of benzoic acid in water at this condition is 1.0x10?? m²/s. The viscosity of water at 20°C is 1 cp, and density of 1000 kg/m³. a. The convective mass transfer coefficient of the system b. The mass transfer flux of benzoic acid to the water flow of the system c. The concentration of benzoic acid in the exit water.

The rate at which solid dissolves from a flat plate of solid benzoic acid into water flowing past the solid at 300 K and atmospheric pressure is found to be 1.8*10^-6 kmol/(m^2·s). The solubility of benzoic acid in the water is 2.95*10^-2 kmol/m^3. The diffusivity of benzoic acid in water is 1.245*10^-9 m^2/s. Assume dilute solution. Find the following: 1. Mass transfer coefficient (m/s) 2. Contact time according to penetration theory. 3. Fractional Rate of surface renewal according to surface renewal theory.

A large volume of pure water at 26.1°C is flowing parallel to a flat plate of solid benzoic acid, where L = 0.244 m in the direction of flow. The water velocity is 0.061 m/s. The solubility of benzoic acid in water is 0.02948 kg mol/m³. The diffusivity of benzoic acid is 1.245 × 10⁻⁹ m²/s. Calculate the mass-transfer coefficient k_L and the flux N_A.

Pure water at 26.1 °C is flowing at a volumetric flow rate of 0.07 m^3/hour through a packed bed of benzoic acid spheres. The spheres are 0.25 inches in diameter and have a total surface area of 0.129 m^2. The solubility of benzoic acid in water is 0.00184 kg-mol benzoic acid per m^3 solution. The outlet concentration CA2 is 1.80x10^-4 kg-mol/m^3. Calculate the mass transfer coefficient k. (answer k=0.053 m/hr)
