PTFE Rod Weight Calculator
A PTFE rod weight calculator is a helpful tool for determining the weight of polytetrafluoroethylene (PTFE) rods. This calculation is essential for engineers, manufacturers, and individuals working with PTFE materials in industrial or custom projects.
Formula
The formula to calculate the weight of a PTFE rod is:
PTFE-W = π × D² / 4 × L × d
Where:
- PTFE-W = Weight of the rod in grams
- D = Diameter of the rod in centimeters
- L = Length of the rod in centimeters
- d = Density of PTFE (usually around 2.2 g/cm³)
How to Use
- Measure the diameter and length of the PTFE rod in centimeters.
- Obtain the density of PTFE, typically 2.2 g/cm³.
- Input these values into the calculator.
- Click “Calculate” to find the rod’s weight in grams.
Example
For a PTFE rod with a diameter of 10 cm, a length of 20 cm, and a density of 2.2 g/cm³:
PTFE-W = π × 10² / 4 × 20 × 2.2 = 3455.75 grams
The calculated weight of the PTFE rod is approximately 3455.75 grams.
