1. What is Height of Lower Part of Vessel?

Definition: This calculator determines the height of the lower part of a vessel based on wind load, shape factor, vibration characteristics, wind pressure, and vessel diameter.

Purpose: It helps engineers design vessels to withstand wind forces by calculating the appropriate height for structural stability.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h1 = \frac{Plw}{k1 \times kcoefficient \times p1 \times Do} \]

Where:

\( h1 \) — Height of Lower Part of Vessel (meters)
\( Plw \) — Wind Load acting on Lower Part of Vessel (Newtons)
\( k1 \) — Coefficient depending on Shape Factor (±5%)
\( kcoefficient \) — Coefficient Period of One Cycle of Vibration (±5%)
\( p1 \) — Wind Pressure acting on Lower Part of Vessel (Pascals)
\( Do \) — Outside Diameter of Vessel (meters)

Explanation: The wind load is divided by the product of shape coefficient, vibration coefficient, wind pressure, and vessel diameter to determine the appropriate height.

3. Importance of Height Calculation

Details: Proper height calculation ensures vessel stability under wind loads, prevents structural failure, and meets engineering safety standards.

4. Using the Calculator

Tips: Enter all required values with appropriate units. The coefficients typically have ±5% tolerance. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why do the coefficients have ±5% tolerance?
A: The coefficients account for variations in material properties, manufacturing tolerances, and environmental conditions.

Q2: How is wind load determined?
A: Wind load is calculated based on wind speed, vessel surface area, and drag coefficient, typically using engineering standards.

Q3: What affects the vibration coefficient?
A: Mass distribution, stiffness, damping characteristics, and natural frequency of the vessel influence the vibration coefficient.

Q4: How does diameter affect the height calculation?
A: Larger diameters generally require shorter heights for the same wind load, as the wind force is distributed over a larger area.

Q5: Can this calculator be used for any vessel shape?
A: It's primarily for cylindrical vessels; other shapes may require different shape coefficients.
