073. Solving a chemistry problem

14. Calculate the flow potential with and without surface conductivity for a quartz diaphragm in a sodium chloride solution at a pressure of 15 kPa. The value of the electrokinetic potential is 60 mV, the dielectric constant of the medium is 81, the viscosity of the medium is 10-3 Pa*s, the specific electrical conductivity of the electrolyte is 2*10-2 Ohm-1*m-1, the surface conductivity is 0.01 Ohm-1*m-1 . Dielectric constant in vacuum 8.85 * 10-12 F/m.
