To calculate the Roll Length (L):
\[ L = \pi \left( \frac{OD^2}{4} - \frac{ID^2}{4} \right) \div t \]
Where:
Roll length is defined as the length of a material that has been rolled into a cylindrical form with a given material thickness. It is calculated by multiplying the difference between the squares of the outer and inner diameters divided by 4, by π, and then dividing by the thickness.
Let's assume the following values:
Using the formula:
\[ L = \pi \left( \frac{1^2}{4} - \frac{0.5^2}{4} \right) \div 0.01 = 98.17 \text{ meters} \]
The Roll Length is 98.17 meters.
Let's assume the following values:
Using the formula:
\[ L = \pi \left( \frac{2^2}{4} - \frac{1^2}{4} \right) \div 0.05 = 47.12 \text{ meters} \]
The Roll Length is 47.12 meters.
