  2. Reminder ..

  3. Area Study

  4. Al Remal Al Janoubi

  5. 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

  6. Continue.. • Population in Area under consideration:

  7. Population Density • Saturationpopulation Total Residential Area = 519,917 m2 Total number of population under saturation condition = 45,721 + 59,918 = 105,639

  8. 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 = ??!!

  9. 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.

  10. Example:

  11. Example:

  12. Network Layout:

  13. Area around nodes:

  14. 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

  15. Assignment: • Network layout. • Area around nodes. • Demand over nodes. • Due date: 07/5/2011
