Hi Kevin, there is no special equation just for "rolled" type capacitors,
you just use the equation for a flat plate capacitor and use the
appropriate area, realizing that a "rolled" capacitor is simply a long two
plate capacitor rolled up.
0.224 x K x A
C = ------------- x (N - 1)
D
C = Capacitance (in microfarads)
K = Dielectric constant
D = Distance between plates in inches
A = Area of plate in inches
N = Number of plates
Sincerely
