Calculation Formula

Pressure Diameter (Dp) = Outer Diameter (Do) - 2 × Wall Thickness (t)

Where:
Dp = Pressure Diameter
Do = Outer Diameter
t = Wall Thickness

Pipeline Pressure Diameter Calculator Usage Guide

Learn how to use the Pipeline Pressure Diameter Calculator and its working principles

How to Use This Calculator

  1. Enter the Outer Diameter of your pipeline in either inches or millimeters.
  2. Enter the Wall Thickness of your pipeline in the same unit as the outer diameter.
  3. Select the appropriate Unit (inches or millimeters) from the dropdown menu.
  4. Click the Calculate button to compute the pressure diameter.
  5. The result will be displayed in the same unit as your inputs.

Understanding Pressure Diameter

Pressure diameter is a measure used in fluid dynamics that represents the equivalent diameter of a pipe when considering the effects of pressure on the flow. It's calculated by subtracting twice the wall thickness from the outer diameter.

Applications

This calculator is useful for:

  • Pipeline design and engineering
  • Hydraulic and pneumatic system calculations
  • Determining flow characteristics in pressurized pipes
  • Comparing different pipeline sizes while accounting for wall thickness

Example

If you have a pipeline with an outer diameter of 6 inches and a wall thickness of 0.25 inches, the pressure diameter would be:

Dp = 6 inches - 2 × 0.25 inches = 5.5 inches
