To calculate the outside diameter of a steel coil, you first need to determine the inside diameter (ID) and the thickness of the steel material. The outside diameter (OD) can then be calculated using the formula: OD = ID + 2 × thickness. If the coil is wound in layers, you may also need to account for the number of layers by adding the thickness multiplied by the number of layers to the ID.
L = length of coil D = diameter of coil N = number of turns P = pitch L^2 = (pi*D*N)^2 + (P*N)^2 using AUTOCAD make sure view mode in isometric - type command HELIX - input base diameter - input top diameter - right click mouse, select turn height - input turn height (pitch) - input height of coil you can see length of coil by clicking picture twice to see length in property of helix the different result between formula above and using autocad is 0.23 %
The length of one coil can vary significantly depending on the diameter and spacing of the coil. For instance, a coil of wire with a diameter of 1 meter and 10 turns would have a length of approximately 3.14 meters (using the formula for the circumference of a circle, ( C = \pi \times d )). To determine the exact length of a specific coil, you would need to know its dimensions.

Typically needs "A" coil atop furnace in ductwork, large vapor and small liquid copper lines running between a-coil and external (outside) condensor/compressor unit, 220 V at compressor end, and a professional to silver braze the commpr connections, evacuate the system, and install the refrigerant.The all you need is a thermostat.
you have to measure the diameter of the coil and then multiply the diamter by pi
You're essentially trying to calculate the diameter of a cylinder with a hole in the middle. There are two formulas for volume which you need. Volume= Pi * r2 * h (where Pi=3.142, r = radius of the coil, h = width of the coil) Volume= Weight/Density Since both these formula equal Volume: Weight/Density= Pi * r2 * h Since the weight you have is for a cylinder with a hole in it, you need to calculate the volume of the whole cylinder (without the hole) and subtract the volume of the hole. So for a steel coil Weight/Density = (Pi * rc2 * h)-(Pi * rh2 * h) where rc= the radius of the coil and rh = the radius of the hole (Radius=diameter/2) you're trying to calculate the radius of the coil, so rearrange the formula to get: ((Weight/Density)/Pi*h) + rh2 = rc2 The diameter of the coil = 2 *rc NOTE:- It's important to keep your units of measure consistent throughout the calculation. Density is generally represented by kilograms per cubic metre (kg/m3) - for us metric users ;-) Therefore keep your coil weight in kgs and your radius / width measures in metres.
You can use the formula for the length of a helix: length = (number of turns) x (coil diameter) x (π). Count the number of turns in the coil, measure the outer diameter of the coil, and use these values in the formula to calculate the approximate length of the wire.

The diameter of a spring coil does not directly affect the force constant of the spring. The force constant is primarily determined by the material of the spring and the number of coils. However, a larger diameter may result in a softer spring with more flexibility.
The mean coil diameter of a spring is the average diameter of the coil measured at its center, excluding any ends or sections that may have a different diameter due to the spring's design. It is an important dimension in determining the spring's performance characteristics and is usually calculated by measuring the outer diameter and subtracting the wire thickness.
