Length of wire in a coil of known dimensions?

Click For Summary
SUMMARY

The length of wire required to create a coil around a solid cylinder can be calculated using the formula W = ∏(D + T/2)(L/T), where W is the length of wire, D is the diameter of the pipe, L is the length of the pipe, and T is the thickness of the wire. This formula applies under ideal conditions for a single layer of wire. To account for multiple layers, a linear combination approach must be utilized, incorporating an integer multiple of the wire thickness. Consistency in units is crucial, with a recommendation to use centimeters for all measurements.

suppose that i have a wire with a known thickness ... and i want to wind it around a solid cylinder with known dimensions, and in the end make a coil with the same length as the solid cylinder

how do i relate between the length of wire required and the diameter of this coil?
 
Engineering news on Phys.org
W = Length of Wire
D = Diameter of Pipe
L = Length of Pipe (and wire coil)
T = Thickness of Wire
∏ = pi

W = ∏(D+T/2)(L/T)

This should give you what you need under ideal situations

The length of the wire is equal to the length of one loop of wire around the tube, ∏(D+T/2), times the number of times it is able to go around the tube, (L/T).

Be sure that your units are all the same (use some common measurement like 'cm' for all of these).
 
that seems to only apply for a single layer of wire coiled onto the core

in order to account for multiple layers of wire, it looks like it will take calculating a linear combination ( http://en.wikipedia.org/wiki/Linear_combination ) where you have an integer multiple of T?
