明渠水流測量 用有限垂線數測驗的速度面積法

Liquid flow measurement in open channels; velocity-area method using a restricted number of verticals

ISO/TR 9823-1990 發布歷史

This Technical Report describes a velocity-area method which can be carried out using three verti-cals only, without significant loss of accuracy, and gives advice on when such a "short-cut" method should be used. The method specified in this Technical Report is not an alternative to the velocity-area method specified in ISO 748, which gives accurate results and should be used under normal conditions. This short-cut method has a limited field of application and is in-tended for use only in special circumstances, ex-amples of which are given in clause 7.

ISO/TR 9823-1990由國際標準化組織 IX-ISO 發布于 1990-09，并于 1990-09-01 實施。

ISO/TR 9823-1990 在中國標準分類中歸屬于: B05 農林技術，在國際標準分類中歸屬于: 17.120.20 明渠中流量的測量。
