Dielectric question

Foxdove

Consider having a hollow silicone tube of 7 mm diameter and a wall thickness of 1.5 mm. There are two copper foil plates that are both 64 mm^2 in area. Will a fluid, such as distilled water, passing through said tube have an measurable influence on producing a change in capacitance?

Note: k = 2.85 for silicone and 80 for distilled H2O. Will said capacitance be different before and during the presence of the H2O?

Where are the copper plates? Whose capacitance?
