Which is used for measuring the rate of flow of water in rivers or streams
Answers
Answer:
The current meter is used for measuring the rate of flow of water in rivers or streams.
Answer:
The answer is a weir, it is used for measuring the rate of flow of water in rivers or streams.
Explanation:
Weirs, also known as low head dams, are of many designs but the most common is that in which water flows above the weir crest top before cascading down to a lower level. It is used by engineers and hydrologists to measure the volumetric flow rate of water in rivers and streams.
It alters the water flow after being used as a barrier across the river width and increases river level height.
The formula to measure volumetric flow rate is;
Q = CLHⁿ
Where Q is the volumetric flow rate, L is the crest width, C is the flow coefficient, H is the head of water height over the crest, and the value of n varies with the structure of the weir.
