What is BS 3680-4F- Round nose horizontal broad-crested weirs about?
BS 3680-4F is an International Standard that discusses the measurement of liquid flow in open channels.
BS 3680-4F deals with the measurement of flow in rivers and artificial channels under steady flow conditions using round-nose horizontal broad-crested weirs.
The flow conditions considered in BS 3680-4F are limited to steady flows which are uniquely dependent on the upstream head.
BS 3680-4F describes round-nose horizontal broad-crested weirs that have a good discharge range and their modular limit and are appropriate for use in small- and medium-sized installations. Round-nose horizontal broad-crested weirs are particularly robust and insensitive to minor damage.
Who is BS 3680-4F- Round nose horizontal broad-crested weirs for?
BS 3680-4F on round-nose horizontal broad-crested weirs is relevant to:
- Manufacturers and designers of open channel flowmeters
- Water structure designers
- Designers of broad-crested weirs
- Installers of weirs
- Hydrologists
- Testing authorities
Why should you use BS 3680-4F- Round nose horizontal broad-crested weirs?
The round nose broad-crested weirs are round edges hydraulic structures that are utilized for controlling the depth, and measurement of liquid flow in open channels and laboratory canals.
The upstream is rounded in such a manner that the flow separation does not occur.
BS 3680-4F provides you with guidance on the measurement of liquid flow in open channels using the round nose horizontal broad-crested weirs. BS 3680-4F assists with the installation and installation conditions of the weirs. The weir is in a straight section of the channel, avoiding local obstructions, roughness, or unevenness of the bed.
BS 3680-4F helps with the measurement of the head and maintenance of the measuring structure. BS 3680-4F also gives information on the velocity distribution. This helps the users to measure the liquid flow in the channels with precision.
