供水管井进水流速的计算及确定 ,对正确进行管井设计具有非常重要的意义。该文从理论上探讨了供水管井进水流速的定义及其计算 ,通过对我国大量管井的调查和复核计算 ,论证了符合我国实际情况的允许井壁进水流速计算公式和允许过滤管进水流速
The calculation and determination of inflow velocity of water supply pipe well have very important significance for the correct design of pipe well. This paper theoretically explores the definition and calculation of feedwater flow rate in water supply pipe well. Through the investigation and review of a large number of tube wells in our country, the calculation formula of allowable water inlet velocity of wellbore and the admittance of filter pipe Flow rate
