Water-Supply Network Design Flow

From demand tables to concentrated, max-hour, specific, route and nodal flows.

Step 1 · Concentrated flow at nodes

Node	Name	Project flow (m³/d)	Hours (h)	Kh	Max-hour (L/s)

Total concentrated (L/s)

—

L/s

Step 2 · Max-hour total demand

Category	Max daily demand (m³/d)	Kh	Max-hour (L/s)

Total max-hour (L/s)

—

L/s

Total max-day (m³/d)

—

m³/d

Step 3 · Specific discharge & route flows

Specific discharge (L/s·m)

Pipe	From	To	Length L (m)	Distribution length (m)	Route flow (L/s)

Step 4 · Nodal flow

Node	Concentrated (L/s)	Adjacent pipes (comma list)	Node flow (L/s)

Max-hour L/s = (m³/d)·Kh/(24·3.6); 比流量 qs = (Qmax − Qconc)/Σ配水长度; 沿线流量 = qs·配水长度; 节点流量 = 集中流量 + ½Σ相邻管段沿线流量.
