Calculating Courses per cm in Knitted Fabric
This solution explains how to find the courses per cm (CPC) in a knitted fabric using the provided loop shape factor (LSF) and wales per cm (WPC).
Fabric Parameters Identification
- Given Loop Shape Factor (LSF) = 1.25
- Given Wales per cm (WPC) = 10
- Target: Calculate Courses per cm (CPC)
Formula for Courses per cm
The relationship between LSF, WPC, and CPC in certain contexts is given by:
$LSF = \frac{CPC}{WPC}$
To find the CPC, we rearrange the formula:
$CPC = LSF \times WPC$
Step-by-Step Calculation
- Substitute the given values into the rearranged formula:
$CPC = 1.25 \times 10$
- Perform the multiplication:
$CPC = 12.5$
- Round the result to one decimal place (as required by the question). The result is already at one decimal place.
$CPC = 12.5$
Therefore, the courses per cm is 12.5.
