Population Density

Calculation of total number of residents:

- Normal Increase ( using equations)
Example:

- Total Area of Southern Remal = 2,754 Dounm

- Total population in Southern Remal in 2002 = 17,500
- Total population in Southern Remal in 2008 = 29,300

Hypothetical figures

Statistical Data

Continue..

- Population in Area under consideration:

Population Density

- Saturationpopulation
Total Residential Area = 519,917 m2

Total number of population under saturation condition = 45,721 + 59,918 = 105,639

Population Density

Therefore,

Population density= Population / Total Area

= 99,435 / 641,000 = 0.155 person/m2

For your project use the following data;

- Total Area of Southern Remal = 2,754 Dounm
- Total population in Southern Remal in 2002 = 17,500 inh.
- Total population in Southern Remal in 2008 = 29,300 inh.
- Regular buildings,
- # of stories = 5
- apartment area = 150 m2
- # of family members = 7
- Population density = ??!!

Allocation steps:

- Draw network layout for the target year and pinpoint junctions and pipelines.
- Draw areas around the nodes in a way that cover the entire area under consideration.
- Determine the water demand type of each junction using the land use map prepared and determine the areas that are served by each junction.
- Calculate the number of population served by each junction (using the area and the density)
- Calculate the demand of each junction by multiplying the population by the average consumption per capita.
- Specify other types of demand and allocate them to the nearest nodes.
- The demand of each junction should be multiplied by a coefficient accounts for UFW in the design year.

Demand over nodes

- Domestic Consumption in the design year = 150L\c\day.
- School consumption = 10 L\pupil\day
- Mosque consumption = 25 L\prayer\day
- UFW =30 %

184*150*1.3

Assignment:

- Network layout.
- Area around nodes.
- Demand over nodes.
