摘要
通用莫迪图使用范围广,但一般需用内插法查图计算求阻力系数λ,为了更进一步提高查图的精确度,以柯列布鲁克-怀特公式为基础,利用CAD技术编程,由计算机绘制了精确度较高的常用普通钢管莫迪图。
Universal Moody diagrams are used in a wide range,but it is generally necessary to use interpolation method to look up the drawing to calculate the resistance coefficientλ.In order to further improve the accuracy of the drawing,the author uses the Colebrook-White formula as the basis,uses CAD technology to program,make use of computer draw a Moody diagram of common steel pipes with high accuracy.
