1. What is the Water Tank Sizing Formula?

The water tank sizing formula calculates the required storage volume based on daily water demand and the number of storage days needed. This ensures adequate water supply during periods of high demand or supply interruptions.

2. How Does the Calculator Work?

The calculator uses the water tank sizing formula:

Where:

• \( V \) — Required tank volume (m³)
• \( \text{demand} \) — Daily water consumption (m³/day)
• \( \text{days} \) — Number of storage days required

Explanation: The formula multiplies daily water demand by the number of days the tank needs to supply water, providing the total storage volume required.

3. Importance of Proper Tank Sizing

Details: Proper water tank sizing is essential for ensuring continuous water supply, managing peak demand periods, providing emergency reserves, and optimizing system efficiency.

4. Using the Calculator

Tips: Enter daily water demand in m³/day and the required storage days. Both values must be positive numbers (demand > 0, days between 1-365).

5. Frequently Asked Questions (FAQ)

Q1: What factors affect daily water demand?
A: Daily water demand depends on population size, usage patterns, climate conditions, and specific water needs (residential, commercial, industrial).

Q2: How many storage days should I consider?
A: Storage days depend on local water supply reliability, emergency requirements, and peak demand patterns. Typically 1-7 days for most applications.

Q3: Should I include a safety factor?
A: Yes, it's recommended to add a 10-20% safety factor to account for unexpected demand increases or supply interruptions.

Q4: What about evaporation losses?
A: For open tanks in hot climates, consider adding 2-5% extra capacity to compensate for evaporation losses.

Q5: Can this formula be used for all tank types?
A: Yes, the formula applies to various tank types (concrete, plastic, steel) but actual dimensions may vary based on tank shape and design.
