14. Under what pressure should the KCl solution be pushed through the ceramic membrane, so that the current potential of the Jet is equal to 4 • 10 ^ -3 B? In this case, the ξ potential is 6.2 × 10 -3 B; the specific electrical conductivity of the medium is κ = 1.5⋅10 -2 ohm-1 m-1; viscosity of the medium η = 10 ^ -3 Pa · s; ε = 81; ε0 = 8.85⋅10 ^ -12 F / m
