1. What is Depth of Elliptical Head?

Height of Formed Head is a type of plain head or plain formed head which is used for horizontal cylindrical storage vessel /shell operating under atmospheric pressure. It represents the depth of the elliptical head in pressure vessel design.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( h_o \) — Height of Formed Head (m)
• \( D_o \) — Outer Shell Diameter (m)

Explanation: The depth of a standard elliptical head is exactly one-fourth of the outer shell diameter, making this calculation straightforward and essential for pressure vessel design.

3. Importance of Head Depth Calculation

Details: Accurate head depth calculation is crucial for pressure vessel design, ensuring proper volume capacity, structural integrity, and compliance with engineering standards for elliptical heads.

4. Using the Calculator

Tips: Enter the outer shell diameter in meters. The value must be positive and greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is an elliptical head used for?
A: Elliptical heads are commonly used in pressure vessels and storage tanks as end closures that provide good pressure distribution and structural strength.

Q2: Why is the depth exactly one-fourth of the diameter?
A: This 2:1 elliptical ratio is a standard in pressure vessel design, providing optimal stress distribution and manufacturing efficiency.

Q3: Are there other types of vessel heads?
A: Yes, other common types include hemispherical heads, torispherical heads, and flat heads, each with different depth calculations and applications.

Q4: What units should be used for input?
A: The calculator uses meters for consistency with engineering standards, but you can convert from other units before input.

Q5: Is this formula applicable to all elliptical heads?
A: This formula applies specifically to standard 2:1 elliptical heads, which are the most common type used in pressure vessel design.
