Water Tank Capacity Formula:
| From: | To: |
Water tank capacity refers to the volume of water a tank can hold, typically measured in litres. For cylindrical tanks, this is calculated using the formula for cylinder volume converted to litres.
The calculator uses the cylindrical tank capacity formula:
Where:
Explanation: The formula calculates the volume of a cylinder (πr²h) in cubic meters and converts it to litres by multiplying by 1000.
Details: Accurate tank capacity calculation is essential for water storage planning, determining water requirements, sizing pumps and pipes, and ensuring adequate water supply for residential, commercial, or agricultural use.
Tips: Enter the radius and height of your cylindrical water tank in meters. Ensure both values are positive numbers. The calculator will provide the capacity in litres.
Q1: Why multiply by 1000 in the formula?
A: The multiplication by 1000 converts cubic meters to litres, since 1 cubic meter equals 1000 litres.
Q2: Can this calculator be used for rectangular tanks?
A: No, this calculator is specifically for cylindrical tanks. For rectangular tanks, use length × width × height × 1000.
Q3: What is the typical capacity range for residential water tanks?
A: Residential water tanks typically range from 1000 to 5000 litres, depending on household size and water usage patterns.
Q4: How accurate is this calculation for real-world tanks?
A: This provides theoretical maximum capacity. Actual usable capacity may be slightly less due to tank design, fittings, and safety margins.
Q5: What if my tank measurements are in centimeters?
A: Convert centimeters to meters by dividing by 100 before entering values, or modify the formula to work with centimeters directly.
