Advantages, Disadvantages and Uses of Broad Crested Weir
Advantages: 1. The head loss across the structure is usually small. 2. You can install Broad crested weir in channels with flat slopes without affecting the upstream flow depth. 3. Easy checking of the measurement precision. 4. A theoretical calibration based on post-construction dimensions can be obtained and the accuracy of the calibration is such that the discharg…

Why Is It necessary To Calibrate Weir
Generally, the dimension of structure where the primary function of flow measurement is standardized but the material from which these devices are constructed may vary. Besides, the flow pattern varies with discharge. Therefore, the calibration equation is derived to easily calculate discharge by only measuring the depth of water.

Which One is More Significant Between Reynolds number and Froude Number in Determining Flow Behavior of a River
Reynolds Number is the effect of viscous force relative to the inertia force . Most open channel flows such as rivers and waterways are turbulent. For this reason, the Reynolds Number of most open channel flows is high which indicates the viscous force is weak relative to the inertia force . It does not play a significant role in determining flow behavior. Based on …

How Can You Determine That The Flow in a River is Subcritical, Critical or Supercritical Without Taking Any Measurement
Generally, Froude number (Fr) is used to determine the water flow state(Subcritical, Critical, or Supercritical) . But without using this Froude number (Fr) , it is possible to calculate the water flow state. You have to create a disturbance on the upstream side and observe the wave of water flow. If the wave of water flow propagates on both upstream and downst…

Why the State of Flow and Critical Depth of A River Need to be Determined
The state of flow is very important as flow behavior depends on it. In order to construct different structures in rivers and canals and to predict the river response the state of flow must be known. Determination of the state of flow experiment is conducted by using a broad crested weir. We can get critical depth in this experiment which is very useful in determi…
