6. IV. Residential Zone:
Assumptions:
1. 80% of officers & employees and 50%
of the workers will be accommodated
2. Average household sizes(persons)
according to BBS HIES 2005:
i. For upper class- 4.9
ii. For middle & semi low class-5.1
iii. For low class- 5.4
Upper Class Apartments:
Total Officers= 118
Total persons= 118*.8*4.9=466
Middle class apartments:
Total Employees= 210
Total persons= 210*0.8*5.1=857
Semi Low Class Apartments:
Total workers= 103
Total persons= 103*0.5*5.1=266
Low Class Apartments:
Total workers= 492
Total persons= 492*0.5*5.4=1329
Total residential population excluding officers,
employees & workers,
Chairman’s Residence= (10-1) = 9
Executive officers apartments= (40-5) = 35
Upper class apartments= (466-95) = 371
Middle class apartments= (857-168) = 689
Semi low class apartments= (266-52) = 214
Low class apartments= (1329-246) = 1083

7. Assumptions:
1. Growth rate formula: For residential & common services zone
Growth rate formula= (1+r)^n
Where, r= growth rate
n= no. of years
2. Linear growth: For production working population
3. 40% increase in production after 10 years

Water demand calculation

12. Calculation of water demand for fire fighting:
Assumptions:
- Only one fire incident occurs per day
- Each station/facility should be served by two fire hydrants at a time.
- Nozzle diameter of the hydrant is 3 inches.
- Velocity of water in the pipe is 3 fps
- Each hydrant will supply water for 30 minutes.
5. Fire Fighting water demand
Discharge of each hydrant, Q=A*V= 0.147ft3/sec
Volume of water of each hydrant= Q*t=0.147*30*60= 265ft3*28.32= 7505 litre
