Calculate Volume of Horizontal Cylinder Tank

Cylinder Volume Formulas:

Full Tank: \[ V = \pi \times r^2 \times L \]

Partial Fill: \[ V = L \times \left( r^2 \times \cos^{-1}\left(\frac{r-h}{r}\right) - (r-h) \times \sqrt{2 \times r \times h - h^2} \right) \]

1. What is a Horizontal Cylinder Tank Volume Calculator?

Definition: This calculator computes the volume of liquid in a horizontal cylindrical tank, either full or partially filled.

Purpose: Essential for industrial, chemical, and storage applications where accurate volume measurements are needed.

2. How Does the Calculator Work?

The calculator uses different formulas based on fill level:

Full Tank: \[ V = \pi \times r^2 \times L \]

Partial Fill: \[ V = L \times \left( r^2 \times \cos^{-1}\left(\frac{r-h}{r}\right) - (r-h) \times \sqrt{2 \times r \times h - h^2} \right) \]

Where:

\( V \) — Volume (cubic units)
\( r \) — Tank radius (units)
\( L \) — Tank length (units)
\( h \) — Liquid height (units)

Explanation: For full tanks, we use standard cylinder volume. For partial fills, we calculate the area of the circular segment and multiply by length.

3. Importance of Tank Volume Calculation

Details: Accurate volume calculations are crucial for inventory management, process control, and safety compliance in industrial settings.

4. Using the Calculator

Tips: Enter tank radius and length. For partial fills, enter liquid height. Leave height empty for full tank calculation. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Any consistent unit (inches, feet, meters). Results will be in cubic units of your input.

Q2: How accurate is the partial fill calculation?
A: The formula is mathematically precise for perfect cylindrical tanks.

Q3: What if my tank has rounded ends?
A: This calculator assumes flat ends. For rounded ends, additional calculations are needed.

Q4: Can I calculate gallons/liters instead?
A: First calculate cubic units, then convert (1 cu ft ≈ 7.48 gallons, 1 cu m = 1000 liters).

Q5: What if height exceeds diameter?
A: The calculator automatically switches to full tank calculation when height ≥ 2×radius.
