Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This article contains the experimental research of water flowing through a weir in a rectangular open channel. Nine regimes of water flowrate investigated in this study. Upstream water levels partially determined for each regime. The coefficient of discharge to the weir determined from the flowrate equation. The determined coefficient of discharge value compared to the value from the Rehbock formula. The diagram of values shows the dependence of the coefficient of discharge Cd on the upstream water level yc/h. Experimental study conducted on the Armfield S16 hydraulic flow demonstrator and hydraulic bench F1-10.
