1. What is Circumferential Stress Due To Fluid Pressure?

Circumferential stress due to fluid pressure is a kind of tensile stress exerted on a cylinder due to fluid pressure. It represents the stress acting along the circumference of the cylinder when subjected to internal or external pressure.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sigma_c \) — Circumferential stress due to fluid pressure (Pa)
• \( F \) — Force (N)
• \( L \) — Length of wire (m)
• \( t \) — Thickness of wire (m)

Explanation: This formula calculates the circumferential stress in a cylindrical pressure vessel by dividing the applied force by twice the product of the length and thickness of the wire.

3. Importance of Circumferential Stress Calculation

Details: Accurate calculation of circumferential stress is crucial for designing pressure vessels, pipes, and cylindrical containers to ensure they can withstand internal or external pressure without failure.

4. Using the Calculator

Tips: Enter force in Newtons (N), length in meters (m), and thickness in meters (m). All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is circumferential stress in pressure vessels?
A: Circumferential stress (hoop stress) is the stress acting along the circumference of a pressure vessel when subjected to internal or external pressure.

Q2: How does this differ from longitudinal stress?
A: Circumferential stress acts around the circumference, while longitudinal stress acts along the length of the cylinder. They have different magnitudes and formulas.

Q3: What are typical applications of this calculation?
A: This calculation is used in designing pipes, boilers, storage tanks, and any cylindrical structures that contain pressurized fluids.

Q4: What factors affect circumferential stress?
A: Circumferential stress depends on the internal pressure, cylinder diameter, and wall thickness of the pressure vessel.

Q5: How is this related to material strength requirements?
A: The calculated stress must be less than the allowable stress of the material to ensure safe operation and prevent failure under pressure.
