1. What is a Water Tank Size Calculator?

Definition: This calculator determines the required water tank capacity based on daily water consumption and the number of days between refills.

Purpose: It helps homeowners, farmers, and businesses properly size their water storage tanks to meet their needs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Tank size (liters)
• \( C \) — Daily water consumption (liters/day)
• \( D \) — Number of days between refills

Explanation: The daily consumption is multiplied by the number of days to determine the total water storage needed.

3. Importance of Proper Tank Sizing

Details: Correct tank sizing ensures adequate water supply, prevents shortages, and optimizes storage costs.

4. Using the Calculator

Tips: Enter your average daily water consumption in liters and the number of days you want the tank to last between refills. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I estimate my water consumption?
A: Track your water meter readings over several days or use average consumption values (e.g., 150L/person/day for households).

Q2: Should I add a safety margin?
A: Yes, consider adding 10-20% to the calculated size for unexpected increases in usage or delays in refilling.

Q3: What about evaporation losses?
A: In hot climates, you may need to increase tank size by 5-10% to account for evaporation, especially for open tanks.

Q4: How does this work for irrigation tanks?
A: For agricultural use, calculate based on crop water requirements per day multiplied by the irrigation interval.

Q5: Can I use this for rainwater harvesting?
A: Yes, but also consider rainfall patterns - you may need larger storage for dry seasons.
