关于2008注水的《经济管径》

原来的图有点小错，更正后在以下。不过也是个草稿。暂且没时间摆活。。。新附件在这儿： 关于经济DN Q群之《给排水茶馆》，供讨论，2009年9月14日一、【前提】 1、半定量分析，没时间全定量来分析。2、考虑哪个影响因素时，相对来说其他另外因素是不变的。如同分析多元函数一样。二、2008注册给排水的一个题目如下：42. 在选择管道经济管径时，以下说法哪些是错误的？（A）电费越贵，经济管径越小（B）管道造价越贵，经济管径越小（C）投资偿还期越长，经济管径越小（D）管道大修费率越高，经济管径越小三、【结论】1、题目有严重歧义。2、不仅有歧义，而且本身此知识点的理解有重大偏差。3、如果按正常的字面理解，此题目当选择AC，就是AC是错的，BD是对的。四、【分析】 1、以《给水工程》第四版P38那个图5-9分析：

关于系统试验压力的选取

50242和50243的要求不一致，如何选择呢？
