Modified Methods on Testing Roughness Coefficient of Water Pipes in Urban Water Distribution Network

Abstract

With the rapid development of digitalization of water supply industry and the implement of computer control, it is necessary to test roughness coefficient of water pipes in the distribution system. Theory of testing roughness coefficient of water pipes and principle of choosing the testing pipes and the working condition of these methods was introduced. Traditional testing method was improved, and by analyzing these methods, a testing method which was fit for the testing of water pipes in water distribution network of China was presented.
