1. What is a Cylinder Tank Volume Calculator?

Definition: This calculator computes the volume of a cylindrical tank based on its radius and height.

Purpose: It helps engineers, designers, and technicians determine the capacity of cylindrical containers, tanks, and pipes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic units)
• \( r \) — Radius of the base (units)
• \( h \) — Height of cylinder (units)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula calculates the base area (πr²) and multiplies it by the height to get the total volume.

3. Importance of Cylinder Volume Calculation

Details: Accurate volume calculations are essential for storage capacity planning, liquid containment, and structural design.

4. Using the Calculator

Tips: Enter the radius and height in the same units (inches, feet, meters, etc.). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Any consistent units (both radius and height must use the same unit).

Q2: Does this work for horizontal cylinders?
A: This calculates total volume. For partial fills in horizontal cylinders, a different formula is needed.

Q3: How precise is the calculation?
A: It uses PHP's M_PI constant (about 15 decimal places) for high precision.

Q4: Can I calculate diameter instead of radius?
A: Simply divide diameter by 2 to get radius before entering.

Q5: What about tank wall thickness?
A: This calculates internal volume. For external dimensions, subtract wall thickness from radius.
