Question # 2 a) Which component of 'Water Works Project' enables you to estimate the 'quantity of water' or before the design of Water Works Project for the future population 'Pi for the year 2045 corresponding to the present population 'Po' of the 'Present year' 2020? Search it out and write that component only. List out also the factors on the basis of which the 'quantity of water' is estimated. [2.5] Answer: b) Discuss briefly each of the four components of the Water Works Planning', as mentioned in (Part-a) of the same Question # 2. Write that 'component which absence will abandon or fail the 'Water Works Planning' or the 'feasibility' of the 'Water Works Planning' provided the rest of the 'three components' exist. [2.5) Answer: c) Define 'population forecasting'. Why we forecast 'population' for the future time for a newly establishing town? Mention different methods of 'population forecasting'. Which method would you recommend as the most rational method for 'population forecasting'. Comment and justify your answer by arguments. Two mathematical formulae as given are P, = P, + K, (t, - t) and InP, = InP, + K, (t, - t) respectively representing the arithmetic and geometric growth methods of 'population forecasting'. Which of these formulae you will correlate with 'Simple Interest Formula' and 'Compound Interest Formula'. If you are sure your answers are correct, write down those formulae. Compare, discuss and justify. Answer: [2.5) d) Suppose you are provided the following data by census department of Peshawar city for following years: Year 1970 1980 1990 2000 2010 Population 650,000 780,000 950,000 1,200,000 225,000 Being a demographer you were asked to forecast the population for year 2040. How will you 212 ascertain that the population is growing Arithmetically or Geometrically or in other words it is an arithmetic or Geometric growth. Discuss the method you used and answer the question with full justification.
