Al Remal Al Janoubi


Population density

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 density1

Population Density

  • Saturationpopulation

    Total Residential Area = 519,917 m2

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


Population density2

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

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

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
