| Abstract |
In this study, it is necessary to consider the established conditions such as water supply capacity, diameter and types of pipeline, the lenghth of pipeline and various assumption in order to decide the low water level of the economical elevation of distribution reservoir by using water tap distribution. However, as these assumed conditions could be changed considerably according to the regional circumstances, investigating distribution ratio of water tap in each elevation in the distribution reservoir installation area could calculate a general formula in order to obtain the best low water level of the distribution reservoir installation elevation. Therefore, if we investigate the distribution of a water tap in the distribution reservoir installation area 30m(above sea level) to the highest by every l0m by using this general formula it is possible to find out applicable and appropriate low water level of the best installation elevation of the reservoir. Let He(m) be the most economical installation elevation of distribution reservoir in the same distribution sector, R_(W1)(%) be the largest distribution ratio of water tap in the elevation classified by every l0m, R_(W2)(%) be the distribution ratio of water tap in l0m higher than that of R_(W1). Following formula was calculated by analyzing the relationship between He, R_(W1)-R_(W2). He=7,692/(R_(W1)- R_(W2))+84 |
