To calculate the weight of an aluminum coil, you need to know the following parameters:
Diameter of the Coil (D): This is the outer diameter of the coil, including the aluminum material and any packaging.
Inner Diameter of the Coil (d): This is the diameter of the central hole or core of the coil.
Width of the Aluminum Strip (W): This is the width of the aluminum material wound into the coil.
Thickness of the Aluminum Strip (T): This is the thickness of the aluminum material.
Density of Aluminum (ρ): The density of aluminum can vary slightly depending on the alloy, but it is typically around 2.7 grams per cubic centimeter (g/cm³) or 2700 kilograms per cubic meter (kg/m³).
The formula to calculate the weight of the aluminum coil is:
Weight (in kilograms)
Weight (in kilograms)=4π×(D2−d2)×W×T×ρ
Here’s how to use this formula:
Measure or obtain the values for D, d, W, T, and ρ.
Plug these values into the formula.
Calculate the result.
Make sure that all the units are consistent. For example, if you are working with the metric system, ensure that the measurements are in centimeters or meters and that the density is in kg/m³. If you’re using the imperial system, you can use inches and pounds per cubic inch for density.
The result will give you the weight of the aluminum coil in the desired units (kilograms, pounds, etc.).
