46. Solving a chemistry problem

174. An aqueous solution of NaCl under a pressure of 4.9 * 104 Pa passes through a quartz membrane. Calculate the flow potential at the membrane-solution interface, if the electrokinetic potential is 0.04 V, the specific electrical conductivity of the medium is 1*10-2 Sm*m-1, the viscosity is 1*10-3 Pa*s, and the relative permittivity is 80.1.
