Question

How is streaming potential measured?

Answer 1

In steady state, the streaming current equals the conduction current. Measurement of a streaming potential can provide both the zeta potential, ζ, and the net charge density, σd, at the hydrodynamic shear plane. The streaming potential is defined to be positive if the higher potential is at the high pressure side

Answer 2

Hey mate

Here is your answer

The streaming potential E is measured at different gas pressure P.

The helmoltzSmolchvski Formula is used to correlate this relation to the Zeta potential.
