Estimate the average, maximum day, and peak hour water demand for a community of 55,000 populations. Also calculate the design capacity of the water-distribution system and water treatment plant. Use the following data: Given: Fire flow, Q=3.86√P(1-0.01√P). P is population in thousand; Q is fire flow (m³/min) Typical fluctuations in water demand in municipal water supply systems Condition Percent of annual average day Range Typical Daily average in maximum month 110-140 120 Daily average in maximum week 120-170 140 Maximum day in a year 160-220 180 Peak hour within a day 225-321 270° 1.5 X maximum day demand from Eq p = 1800, p: percentage of the annual average demand for time, t, t = time, d. The time t in days varies from 2/24 to 365
