Coil Length Formula
The following two example problems outline the steps and information needed to calculate the Coil Length.
CL = (OD-WD) * pi
- Where CL is the Coil Length (length per coil)
- OD is the outer diameter
- WD is the wire diameter
How to Calculate Coil Length?
The following example problems outline how to calculate Coil Length.
Example Problem #1:
- First, determine the outer diameter.
- The outer diameter is given as: 5.
- Next, determine the wire diameter.
- The wire diameter is provided as: 3.
- Finally, calculate the Coil Length using the equation above:
CL = (OD-WD) * pi
The values provided above are inserted into the equation below and computed.
CL = (5-3) * pi = 6.28 (length per coil)
Example Problem #2:
For this problem, the variables required are provided below:
outer diameter = 6
wire diameter = 4
Test your knowledge using the equation and check your answer with the calculator..
CL = (OD-WD) * pi = ?
