Question

You are assigned to select pipes for delivering water to a newly developed residential community (Class of Construction: 4). The community has 1000 houses; each household has 4 residents on average. For domestic water usage, a high demand of 0.40 m^3 per person per day can be used for the design. The net fire flow (NFF) for this new community is estimated to be 2000 m^3 /d. According to the design guidelines of the local water district, the maximum flow velocity should not exceed 2.4 m/s. The pipe should have a wall thickness of at least 0.6 inch. Using the NPS standard (see attachment), what will you recommend for the smallest pipe size acceptable for this project? 1 meter = 39.37 inches.
