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

Process Selection Considerations
Selection of an activated-sludge process for BOD removal and nitrification is a function of many considerations including specific site constraints, compatibility with the existing process, compatibility with existing equipment, present and future treatment needs, level of capability of the operating staff, capital costs, and operating cost.

Epidemiology
7th m/c cancer in woman, 5th m/c for death (US)
The peak incidence : about 60 yrs old
Postmenopausal >80%
30% Malignancy of ovarian neoplasms in postmenopausal women Cf) 7% in premenopausal
Risk factor: low parity and infertility, (*Oral contraceptive use reduces the risk)
Screen method to test the feasibility of each concept. As a result, the team concluded that ‘nutrition drink’ is the most feasible in both product development and commercialization. After sales forecasting and financial analysis, the team found out that development of nutrition drink is expected to bring more market share (6.8% more) to the company, while fitting for the company’s past aggr
