The following figure shows the plan view of a community of dimensions 1600m 1600m x 1000m 1000m.. The The comm commun unit ity y is supp suppli lied ed with with wate waterr from from the the main main reservoir R-1 located at an elevation of 775m. The population density is 60 per/ha and the water consumption is 200 lt/per/day.

a- Calculate the average daily demand in m /day at node J1 assuming that the total demand is equally distributed between all nodes. b- Assuming all nodes are at an elevation of 750m above sea level, and the distance between R1 and J1 is 5km. Calculate the pipe diameter of pipe P1 having a friction coefficient 3
of 0.005 in order to convey a peak flow of 2880 28 80 m /day and to get a pressure of 2bar at junction J1.
