The formula to calculate capacitance for a flat plate capacitor is;
0.224 x K x A
C = ------------- x (N - 1)
d
C = capacitance (in picofarads)
K = dielectric constant
A = area of plates (in inches)
d = seperation of plates (in inches)
n = number of plates
If the capacitor is made of bottles the calculation becomes complicated by
the bottles shape! Then the area of the plates in the calculation would
become pi (3.1415927) x the inside diameter of the bottle x height it's
filled with salt water then add to this pi x half the inside diameter of
the bottle squared for the area of the bottom of the bottle, then for the
seperation of the plates use the thickness of the bottle's glass.
