尽管计算机正在接管工程师越来越多的计算工作，但为配水系统选择管道尺寸仍然是一个基于经验法则和试错法的过程。配电系统管道尺寸的计算机化程序正在变得可用，但可接受性受到限制，因为很少有优化模型可用作工程师易于应用的用户友好工具。本文描述了一个由作者开发的计算机程序，它遵循了传统的trialand- 管道尺寸调整的错误方法。包括20个参考文献、表格和图表。

In spite of the fact that computers are taking over increasing amounts of the engineer's computational work, selecting pipe sizes for water distribution systems remains a process based on rules of thumb and trial and error. Computerized procedures for sizing distribution system pipe are becoming available, but acceptance is limited because few optimization models are available as user-friendly tools that can be easily applied by engineers. This article describes a computer program developed by the authors that follows the conventional trialand-error approach to pipe sizing. Includes 20 references, tables, figures.
