18. What pressure do I need to apply, pushing through the membrane from barium carbonate 96% ethyl alcohol, so that the flow potential E of the current is 1.9 V? In this case, ξ = 42⋅10 -3 V; the specific electrical conductivity of the medium is ω = 1,1⋅10 -4 Ω -1 ⋅ m -1; the viscosity of the medium is η = 1.2⋅10 -3 Pa⋅s; ε = 81; ε 0 = 8.85⋅10 -12 F / m.
