新设计通用莫迪图

Newly designed universal Moody diagram

流体输送管道沿程阻力系数λ的计算很复杂,如查阅莫迪图,则可简化λ的计算。鉴于当时的条件,以往用手工绘制的莫迪图的精确度不高。如今,计算机已广泛应用于各个领域,为此,作者以柯列布鲁克-怀特公式为基础,利用LISP语言编程,用计算机绘制了精确度较高的莫迪图(简称新设计通用莫迪图)。

The calculation of the drag coefficientλof the fluid conveying pipeline is very complicated.If the Moody diagram is used,the calculation ofλcan be simplified.In view of the conditions at the time,the accuracy of Moody diagrams drawn by hand in the past was not high.Nowadays,computers have been widely used in various fields.For this reason,based on the Colebrook-White formula,the author uses the LISP language to program and draws a highly accurate Moody diagram with a computer(referred to as the new design general Moody diagram).
