Water Demand Equation:
| From: | To: |
Domestic water demand refers to the amount of water required for household purposes such as drinking, cooking, bathing, washing, and sanitation. It is typically measured in liters per day and depends on population size and per capita consumption patterns.
The calculator uses the water demand equation:
Where:
Explanation: The equation calculates total daily water demand by multiplying the population size by the average daily water consumption per person.
Details: Accurate water demand calculation is essential for urban planning, water supply system design, infrastructure development, and sustainable water resource management. It helps ensure adequate water supply for domestic needs.
Tips: Enter population (number of persons) and LPCD (liters per person per day). Typical LPCD values range from 100-200 l/person/day for urban areas, but may vary based on location and lifestyle.
Q1: What factors affect LPCD values?
A: LPCD varies based on climate, economic status, water availability, cultural practices, and efficiency of water use appliances.
Q2: How does population density affect water demand?
A: Higher population density typically leads to higher total water demand, though per capita consumption may vary based on urban vs. rural settings.
Q3: What is considered a typical LPCD value?
A: In developed countries, LPCD typically ranges from 150-300 liters, while in developing countries it may range from 50-150 liters per person per day.
Q4: How does season affect water demand?
A: Water demand often increases during hot/dry seasons due to additional requirements for gardening, cooling, and outdoor activities.
Q5: Why is accurate water demand calculation important?
A: It helps in designing appropriate water supply systems, preventing water shortages, and ensuring sustainable water resource management.
