应用概率方法计算室内给水管道设计秒流量

Applying Probability Method to Calculating the Designed Flowrate of lndoor Water Supply Pipe

本文在深入研究现有室内给水管道设计秒流量计算方法的基础上，应用概率论，以满足使用保证率的室内给水管道设计秒流量为出发点，提出了一种新的计算方法。通过实例计算，分析了使用保证率和卫生器具放水使用概率对设计秒流量的影响，与平方根法和已有概率法作了比较，说明了该方法的合理性和通用性。

On the basis of making a thorough study on the existinf methods for calculating the designed flowrate of indoor water supply pipe, this paper presented a new calculating method based on probability theory. The flowrate calculated by this method is able to meet the guarantee rate of utilization. Through case studies, this paper analysed the effecs of the guarantee rate of utilization and water probability of sanitary fittings on the flowrate, compared with the square root method and the existing probability method, and illustrated the rationality and practicability of this method.
