8. Construct a curve for the dependence of the ξ-potential on the diameter
pores of quartz diaphragm capillaries, using the following experiments
data of electroosmosis:
 
The pore diameter is d⋅10 6, m 3.0 26.0 74.0 128.0
Volumetric velocity V⋅10 9, m 3 / s 0.12 0.18 0.32 0.36
 
The specific electrical conductivity of the medium is ω = 1.8⋅10 -2 Ω -1 ⋅ m -1; amperage
J = 0.32 × 10 -3 A; viscosity of the medium η = 10 -3 Pa · s; ε = 81; ε 0 = 8.85⋅10 -12 F / m.
