基于CAGD的管道摩擦系数确定方法

Method of Finding Friction Factor of Pipe Based on CAGD

采用计算机辅助几何设计的方法 (CAGD法 ) ,对管道摩擦系数曲线图进行计算机精确描绘 ;利用VisualBasic和AutoCAD混合编程进行计算机准确查图 ,VisualBasic编程进行界面设计和前台运算 ,AutoCAD技术进行后台图形处理 。

By method of Compute r Aided Geo metrical Design(CAGD),pipe firction fact ors curves are converted to rester prese ntation.On the foundation,the raster pre sentation is inlaid in AutoCAD,and then the curves are precisely plotted in com puter.Program worked out with Visual Bas ic calculating foreground and AutoCAD d ealing with curves background imitates m an to search for curves,so the friction factor under some given conditions can b e found precisely.
