2. Design a storage and distribution system for the town of Waffle. The requirements are that fire protection shall be provided, the minimum water pressure at the top of the apartments is to be 240 kPa and the maximum system pressure is to be 550 kPa. The following assumptions may be used: Each of the four apartment buildings is occupied by 50 residents. Each apartment building is four stories high. Each story is 3 meters high. Each house is occupied by three residents. Average daily demand for the village is 500 Lpcd and the peak hourly demand factor is 6.2. Needed fire flow for the houses is 230 m3/h. and for apartment building is 500 m3/h, with 2 h duration. System pressure is to be provided from the elevated storage tank. Minor pressure losses in buildings may be ignored. The distribution system will not contain any loops. Assume that emergency supply (ES), fire department supply (FDS) or off peak pumping are not provided (they are all equal to zero). Provide the following information to support your design: • A table (e.g., similar to what's provided in Example 17-4) showing pipe diameters and pressures at critical points • The minimum required volume of the storage tank 450 30 18 m 150 m D 250 m Apartments Opo Road 400 m G 200 m B QOO0625 m 500 m 120 m 120 m Synup River 136 m m3 Design Flow 525.8 hr 100-Year flood Point Elevation Tank 137.0 m A 130.0 m B 122.0 m C 122.3 m D 122.6 m E 126.1 m F 127.1 m G 120.0 m 128 F H 122.5 m Water tower 1 129.0 m Grd El 137 m 100 m Tank A 300 m 375 m

Transcribed Image Text:2. Design a storage and distribution system for the town of Waffle. The requirements are that fire protection
shall be provided, the minimum water pressure at the top of the apartments is to be 240 kPa and the
maximum system pressure is to be 550 kPa. The following assumptions may be used: Each of the four
apartment buildings is occupied by 50 residents. Each apartment building is four stories high. Each story is 3
meters high. Each house is occupied by three residents. Average daily demand for the village is 500 Lpcd and
the peak hourly demand factor is 6.2. Needed fire flow for the houses is 230 m3/h. and for apartment
building is 500 m3/h, with 2 h duration. System pressure is to be provided from the elevated storage tank.
Minor pressure losses in buildings may be ignored. The distribution system will not contain any loops. Assume
that emergency supply (ES), fire department supply (FDS) or off peak pumping are not provided (they are all
equal to zero). Provide the following information to support your design:
• A table (e.g., similar to what's provided in Example 17-4) showing pipe diameters and pressures at critical
points
• The minimum required volume of the storage tank
