Tank Capacity Formula:
| From: | To: |
The tank capacity calculation determines the volume of liquid a cylindrical tank can hold. This calculator specifically calculates capacity in US gallons based on the tank's radius and height measurements in feet.
The calculator uses the cylindrical volume formula:
Where:
Explanation: The formula calculates the volume of a cylinder and converts it from cubic feet to US gallons using the standard conversion factor.
Details: Accurate tank capacity calculation is essential for industrial applications, water storage planning, chemical processing, fuel storage, and agricultural irrigation systems.
Tips: Enter the radius and height in feet. Ensure measurements are accurate and represent the internal dimensions of the tank. All values must be positive numbers.
Q1: Why use 0.133681 as the conversion factor?
A: This factor converts cubic feet to US gallons, where 1 cubic foot equals approximately 7.48052 gallons, and the formula accounts for the cylindrical volume calculation.
Q2: Can this calculator be used for non-cylindrical tanks?
A: No, this calculator is specifically designed for cylindrical tanks. Other shapes require different volume formulas.
Q3: Should I use internal or external dimensions?
A: Use internal dimensions for accurate capacity calculation, as tank walls reduce the actual storage volume.
Q4: How accurate is this calculation?
A: The calculation provides theoretical maximum capacity. Actual usable capacity may be less due to fittings, sediment, or safety margins.
Q5: Can I use this for metric measurements?
A: This calculator requires inputs in feet. For metric measurements, convert to feet first or use a different conversion factor.
