1. What is Part G Water Usage Calculation?

The Part G water usage calculation estimates total water consumption per person per day by summing fixture consumption values and adding a base water usage of 5 liters per person per day.

2. How Does the Calculator Work?

The calculator uses the Part G water usage equation:

Where:

• \( fixture\_consumption \) — Total water consumption from all fixtures (l/person/day)
• \( 5 \) — Base water usage (l/person/day)

Explanation: The equation calculates total daily water usage by combining fixture-specific consumption with a standard base usage amount.

3. Importance of Water Usage Calculation

Details: Accurate water usage estimation is crucial for plumbing system design, water conservation planning, and ensuring adequate water supply for residential and commercial buildings.

4. Using the Calculator

Tips: Enter the total fixture consumption in liters per person per day. The value must be a valid non-negative number.

5. Frequently Asked Questions (FAQ)

Q1: What does the "5" represent in the equation?
A: The "5" represents the base water usage of 5 liters per person per day for essential needs not covered by specific fixtures.

Q2: How is fixture consumption calculated?
A: Fixture consumption is calculated by summing the water usage of all plumbing fixtures based on their flow rates and estimated usage patterns.

Q3: What are typical water usage values?
A: Typical values range from 80-150 l/person/day for residential buildings, depending on fixtures, habits, and conservation measures.

Q4: Does this calculation account for seasonal variations?
A: No, this is a baseline calculation. Seasonal variations and specific usage patterns should be considered separately.

Q5: Is this calculation suitable for commercial buildings?
A: While based on residential standards, the calculation can be adapted for commercial use with appropriate fixture consumption values.
