Formula

Capacitance :
C = 2π εL/In( b/a)

Permittivity :
ε = Cln (b/a)/2πL

Length of Conductors :
L = Cln(b/a)/2π ε

Outer Conductor Diameter :
b = ae (2πL/C)

Inner Conductor Diameter :
a = b/e (2π L/C)

Where,
C = Capacitance,
ε = Permittivity,
L = Length of Conductors,
b = Outer Conductor Diameter,
a = Inner Conductor Diameter.
