本powerpoint演示文稿首先简要概述了水力模型，定义为计算机化管网分析 使用能量损失方程。水力模型用于确定流量， 压力和水质 管道的各个部分 网络介绍了现场测试，包括 流量、压力或水的测量 特定条件下的质量指标。课程包括:水力坡度线（HGL）测试；消火栓（消防）流量试验；关闭阀门；还有来自北卡罗来纳州的例子。包括数字。

This powerpoint presentation begins by providing a brief overview of hydraulic models, defined as computerized pipe network analysis that use energy loss equations. Hydraulic models are used to determine the flow rates, pressures, and water quality in the individual sections of a piping network. Field testing is presented, and includes the measurement of flow, pressure, or water quality indicators under certain conditions. Topics presented include: hydraulic grade line (HGL) tests; hydrant (fire) flow tests; closed valves; and, examples from North Carolina municipalities. Includes figures.
