You are assigned to select pipes for delivering water to a newlydeveloped residential community (Class of Construction: 4). Thecommunity has 1000 houses; each household has 4 residents onaverage. For domestic water usage, a high demand of 0.40 m3 perperson per day can be used for the design. The net fire flow (NFF)for this new community is estimated to be 2000 m3 /d. According tothe design guidelines of the local water district, the maximum flowvelocity should not exceed 2.4 m/s. The pipe should have a wallthickness of at least 0.6 inch. Using the NPS standard (seeattachment), what will you recommend for the smallest pipe sizeacceptable for this project? 1 meter = 39.37 inches.
