1. What is the Seto Yusuke Pressure Calculator?

Definition: This calculator determines internal pressure using Barlow's formula, which relates material stress, thickness, and diameter.

Purpose: It helps engineers and researchers calculate pressure in cylindrical vessels or pipes under stress.

2. How Does the Calculator Work?

The calculator uses Barlow's formula:

Where:

• \( P \) — Internal pressure (Pascals)
• \( S \) — Material stress (Pascals)
• \( t \) — Wall thickness (meters)
• \( D \) — Internal diameter (meters)

Explanation: The formula calculates the maximum internal pressure a cylindrical vessel can withstand before yielding.

3. Importance of Pressure Calculation

Details: Accurate pressure calculations are critical for designing safe pressure vessels, piping systems, and containment structures.

4. Using the Calculator

Tips: Enter material stress in Pascals, wall thickness in meters, and internal diameter in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is Barlow's formula used for?
A: It's primarily used to calculate the bursting pressure of pipes and pressure vessels.

Q2: What units should I use?
A: Consistent SI units are required - Pascals for stress/pressure, meters for dimensions.

Q3: Does this account for safety factors?
A: No, the result is theoretical maximum pressure. Apply appropriate safety factors for engineering designs.

Q4: Can I use this for non-cylindrical vessels?
A: No, Barlow's formula is specifically for cylindrical geometries under internal pressure.

Q5: How do I determine material stress (S)?
A: Use yield strength or allowable stress from material specifications, divided by safety factors.
