oa Civil Engineer in South Africa - A simplified approach to the solution of pipeflow problems using the Colebrook-White method

 

Abstract

The friction head loss in pipes flowing full is most accurately assessed using the Darcy-Weisbach equation in conjunction with the Moody diagram. This method is, however, time consuming and can be greatly improved by plotting charts of head loss against discharge or by using a programmable calculator. This paper presents such a chart as well as a programme for determining head loss on a Hewlett Packard 25 calculator.

Drukverlies as gevolg van wrywing in volvloeiende pype kan met akkuraatheid vasgestel word deur die gebruik van die Darcy-Weisbach vergelyking, tesame met die Moody diagram. Die metode is egter tydrowend en ken grootliks verbeter word deur grafies die stroomverlies teenoor die uitvfoeiing voor te stel, of andersins 'n programmeerbare rekenaar te gebruik.
