A 30 μm thick membrane having 3 m$^2$ surface area is used to separate NaCl at steady state. Mass transfer coefficient on solution side = $1\times 10^{-6}$ m·s$^{-1}$, on membrane side = $3\times 10^{-7}$ m·s$^{-1}$. NaCl concentration = 0.03 g·(100 mL)$^{-1}$; concentration on permeate side = 0. Permeability = $9\times 10^{-6}$ m·s$^{-1}$. Find the rate of NaCl removal (g·h$^{-1}$).
