Formula for Yarn Diameter Calculation
The question provides a specific formula used in textile calculations:
$ \text{Diameter} = \frac{1}{26\sqrt{\text{counts}}} $
This formula directly relates the diameter of a yarn to its count.
- Yarn Count is a measure of the fineness or thickness of a yarn. Different systems exist (e.g., Tex, Ne, Nm), but the formula implies a specific system where count is inversely related to diameter.
- The formula shows that as the yarn count increases (meaning the yarn is finer/thinner), the calculated diameter decreases.
Therefore, the given formula is specifically used to calculate the yarn Diameter.
Answer: The correct option is B: Diameter.
