此powerpoint演示文稿演示了液压系统的实际应用 模型适用于导致 节约成本， 创新，或者 操作规程的改变。 本文举了两个例子，第一个是蒙大拿州的海伦娜，包括: 审查GIS地理数据库中的缺失数据； 为模型连接节点创建形状文件并指定 高程值； 按地块确定的用水量，并分配给 模型连接节点；和 连接的储罐、泵站、减压阀 阀门、水源（模型水库）和其他特征 管道和连接节点。第二个例子是蒙大拿州的哥伦比亚瀑布，包括以下内容:问题-城市想知道操作水泵的最佳方法 火流事件期间； 分析 -长周期模拟， 火灾流动分析； 决心 -根据储罐液位设置井泵 在高火流量下有问题； 后果 -将泵开/关设置更改为 系统压力，以及 提高响应时间并减少压降 1500 gpm时，火流量小于5 psi。包括表格、数字。

This powerpoint presentation demonstrates the practical applications of the hydraulic model to operations of a water utility that result in cost savings, innovation, or a change in the operational protocols. Two examples are presented, the first being Helena, Montana, that included the following: reviewed GIS geodatabase for missing data; created shapefile for model junction nodes and assigned elevation values; defined water consumption by parcel and distributed to model junction nodes; and, connected tanks, pump stations, pressure reducing valves, sources (model reservoirs), and other features to pipes and junction nodes. The second example was Columbia Falls, Montana, and included the following: issue - city wanted to know best way to operate pumps during fire flow event; analysis - Extended Period Simulation, and Fire Flow Analysis; determined - well pumps set based on tank levels problematic during high fire flows; result - changed pump on/off settings to system pressure, and improved response time and reduced pressure drop at 1,500 gpm fire flow to less than 5 psi. Includes tables, figures.
