Water Tank Size Formula:
| From: | To: |
Water tank size calculation determines the appropriate storage capacity needed to meet water demand over a specified period, accounting for safety factors and usage patterns.
The calculator uses the water tank size formula:
Where:
Explanation: The formula calculates the minimum tank capacity required to store water for the specified number of days, multiplied by a safety factor to account for variations in usage and supply.
Details: Proper water tank sizing ensures adequate water supply during periods of low rainfall, water shortages, or emergency situations while avoiding over-sizing that leads to unnecessary costs.
Tips: Enter daily water demand in liters per day, storage period in days, and safety factor (typically 1.1-1.5). All values must be positive numbers.
Q1: What is a typical safety factor value?
A: Safety factors typically range from 1.1 to 1.5, depending on usage variability, climate conditions, and reliability of water supply.
Q2: How do I determine daily water demand?
A: Daily demand can be estimated based on number of users, typical consumption patterns, or historical usage data. Residential use is typically 100-200 L per person per day.
Q3: What storage period should I use?
A: Storage period depends on local rainfall patterns, water supply reliability, and intended use. Typical periods range from 3-10 days for residential use.
Q4: Does this account for evaporation losses?
A: The basic formula doesn't account for evaporation. In hot climates, consider increasing the safety factor or adding an evaporation allowance.
Q5: Can this be used for commercial applications?
A: Yes, the same formula applies, but commercial demands and safety factors may differ significantly from residential applications.
