摘要
直饮水管网的设计瞬时高峰流量 (传统称设计秒流量 )应该用概率法计算。同时用水的龙头数量可按二项分布规律确定 ,其中龙头的使用概率计算涉及到两个重要参数 ;最大用水小时之内更为密集用水的时段T和该时段的累计耗水量αQh,这两个参数需要实地观测确定。所观测的建筑物要有确定的居住率 ,系统应达到一定的规模 ,观测实施时应捕捉住系统的最大用水小时并记录瞬时流量或用量。
Instant delivery (peak flow) in direct drinking water pipeline design should be calculated by way of proba- bility theory and the simultaneous working faucets could be decided on the basis of binominal probable distribution. Two factors, the most intensive time-interval T and the cumulative water consumption of this interval in the maximum water demand hour, are involved while deciding the working faucets. These two have to be examined by field investigation at most representative quarters.
