ISO 4374:1990 Liquid flow measurement in open channels - Round-nose horizontal broad-crested weirs

standard by International Organization for Standardization, 03/01/1990

Full Description

Deals with the measurement of flow in rivers and artificial channels. The flow conditions considered are limited to steady flows which are uniquely dependent on the upstream head. Drowned flows, which depend on downstream as well as upstream levels, are not covered. Cancels and replaces the first edition (ISO 4374 :1982), of which it constitutes a technical revision.
