1. What is Depth of Hemispherical 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.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The depth of a hemispherical head is exactly half of the outer shell diameter, as a hemisphere is half of a sphere.

3. Importance of Depth Calculation

Details: Accurate calculation of head depth is crucial for pressure vessel design, manufacturing, and ensuring proper vessel geometry for optimal performance and safety.

4. Using the Calculator

Tips: Enter the outer shell diameter in meters. The value must be valid (diameter > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is the depth exactly half the diameter?
A: Because a hemisphere is exactly half of a complete sphere, so its depth equals the radius, which is half the diameter.

Q2: What are typical applications of hemispherical heads?
A: Hemispherical heads are commonly used in pressure vessels, storage tanks, and reactors where high pressure resistance is required.

Q3: Are there different types of vessel heads?
A: Yes, besides hemispherical heads, there are elliptical, torispherical, and flat heads, each with different geometric properties.

Q4: What units should be used for input?
A: The calculator uses meters for both input and output, but you can convert from other units as needed.

Q5: Is this calculation applicable to all head types?
A: No, this specific formula applies only to hemispherical heads. Other head types have different geometric relationships.
