Calculate the steady state mass transfer coefficient for diffusion from the wall of a smooth 2 cm tube when the average fluid velocity u=1.9 m/s, p=1020 kg/m³, μ=3 cP and diffusivity (D, 3.0×10 cm³/s). Sh=0.023 Re S a) 4.66×100 cm²/s b) 6.66x100 cm³/s c) 3.36×100 cm²/s d) 4.66x10 cm2/s М 0.14 for smooth tube
