Problem 1
You are in the process of designing a water supply system for the whole Iligan City, and
the design life of your system is to end in the year 2070. The population in the town has
been measured every 10 years since 1980 by the Philippine Statistics Authority, and the
reported populations are tabulated below. Estimate the population in the town using (a)
arithmetic growth projection, (b) geometric growth projection (exponential formula), (c)
declining growth projection (assuming a saturation concentration of 480,000 people), and
(d) logistic curve projection.

- 3. Drinking water is piped from a water main into a house via a PVC (i.e., smooth) pipe. There is a total of 20 linear feet of 1" diameter pipe between the water main and a point just inside the house that is 10 ft above the water main. This drinking water pipe branches from the water main (K₁ = 0.2), a water meter taps into the pipe (KL = 7), there are two 90° bends (K₁ = 1.5), and finally a (fully open) water shutoff ball valve (K₁ = 0.05) before the point just inside the house. The pipe maintains a flow of 0.05 ft³/s. If the goal is for the gage pressure of the water to be 8640 lb/ft² (aka 60 psi) just inside the house, what must the gage pressure of the water be at the water main?
