摘要
(三)小时用水变化规律 小时用水变化规律反映一个城市和居住小区的用水变化状况,以时变化系数K_h表达。在正常情况下,K_h值与城市性质、人口密度、工商业发展状况有相关关系。一般用水人口越多,K_h越小;工商业用水越多,K_h越小。 本研究从两个途径进行。一个途径是通过典型小区实际测定逐时用水变化情况,另一个途径是通过各地自来水公司提供的历年来最高供水日的逐时供水变化情况。现将成果分述如下: 1.居住小区的时用水变化规律 本次研究工作在三个地区分三个类型用水设备分别测定最高日用水的逐时用水状况,共测定28城市、77小区的逐时用水量213个数据。
On the basis of about 100 thousand of data which were treated by mathematical statistics and gathered from the water sale records in 55 cities for years and the observation reports of 77 residential quarters in this country the recommended values of water quota including the domestic water quota of urban inhabitants, the composite domestic water quota and the urban composite water quota and a selective range of 1. 3 to 1. 6 of hourly variation coefficient are proposed.
