How do calculate spiral length of Spiral rings
Formula to calculate length of spiral reinforcement in columns
It depends on the spiral - there are lots of different ones, with different formulae.

Spiral Fracture
A spiral length of something, like a spring.
The length of a tube is not related to its radius so you cannot.
Select any point in the plane as the origin. From the origin, draw a line of unit length. At its end draw a perpendicular line, also of unit length. This is the first line of the spiral. Join the end of this second line to the origin - this will be a line of length sqrt(2). At the end of this line draw a perpendicular line of unit length. This is the second line of the spiral. Join the end of this new line to the origin - this will be a line of length sqrt(3). At the end of this line draw a perpendicular line of unit length. This is the next line of the spiral. Continue until you have had enough! Or, follow the link.
The hypotenuse of the nth triangle has a length of sqrt(n+1)
looking for length of tube if i.d is 93mm and is to hold 1ltr of fluid
You take it and roll it out and use a length measuring tool to measure it's approximate length in yards feet inches centimeters etc... :)
