Calculations of the design of each unit operations
Flowrate
Present Average Flowrate = 4220 m3/d
Water use per capita = 4220/15000 = 0.281333 m3/d capita
Population after 10 years = 15000 Χ 1.0310 = 20158.75 ≒ 21000 capita
∴ Average Flowrate = 0.281333 Χ 21000 = 5908 m3/d ≅6000m3/d
Peak Flowrate = 5908 Χ 1.5 = 8862 m3/d ≅9000 m3/d
