Calculates the outside diameter of a roll of material when the rolled length of the material, thickness of the material, and diameter of the hole in the center or the tube on which the material is wound are given. The number of turns on the roll is also calculated. Variations due to stretching or softness of the material

Look at this image: Let's call the outside diameter of the roll of material D, the inner diameter d, the material's thickness T, and the length of the material L: all of these can then be factored into the following equation: π × (D 2 / 4 − d 2 / 4) = L × T.

For our customers we have developed the Roll Diameter Calculator below. Fill in any three of the four values, and click the "Calculate" button. The missing value will be calculated for you. Since roll diameter is affected by how tight or loose a roll may be wound, these calculations should be used as estimates.

A roll diameter calculator is frequently used to determine the length of the converter material in an existing roll. But it can also be used to get material thickness of the converter material. Instead of manually using a complex formula to get your material estimate, you can quickly get an estimate of roll length or material thickness.

To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.

Determining Roll Diameter. The following is an approximate formula for determining the diameter of a roll of fabric. The formula generally underestimates roll diameter for fabrics with texture or some specialty yarns. Also, actual diameters can vary at different take-up tensions. T = thickness of fabric (inches) Where, Y = linear yards of fabric.

The next equations show how you can instead find the diameter from them. The equation for diameter of a circle from circumference is: d = c / π. d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2 r. d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter ...

2021-1-20 The radius of the roll is. In your example L = 3000 × 12 = 36000 inches, t = 0.005 inches and r = 6/2 = 3 inches. Thus. R = √ (36000 × 0.005/ π + 3 2) = √ (57.30 + 9) = 8.14 inches. Thus the diameter of the roll is 2 × 8.14 = 16.28 inches. Math Central is supported by the University of Regina and The Pacific Institute for the ...
