Critical depth open channel formula
WebIn fluid mechanics and hydraulics, open-channel flow is a type of liquid flow within a conduit with a free surface, known as a channel. [1] [2] The other type of flow within a conduit is … WebThe critical depth for a rectangular channel can be calculated from the fact that the Froude number is equal to one at critical flow conditions. For a rectangular channel , this fact leads to the equation: Vc/ (gyc)1/2 = 1, where the subscript c is used to indicate critical flow conditions for the velocity and depth.

Weblook at every possible instance of critical depth problems. What is critical depth? In open channel hydraulics, critical depth is the depth of flow (for a given discharge) where the specific energy is at a minimum. The total energy head (specific energy) for a cross section is given by: g αV H WS 2 2 = + WebCritical flow depth y c: 0 . Critical flow area A c: 0 . Critical wetted perimeter P c: 0 . Critical top width T c: 0 . Critical hydraulic radius R c: 0 . Critical hydraulic depth D c: 0 . Critical flow velocity V c: 0 . Critical Froude number F c: 0
WebApr 5, 2024 · Explanation: For a given value of specific energy, the critical depth gives the greatest discharge in an open channel, or conversely, for a given discharge, the specific energy is a minimum for the critical depth. So at a control section, the discharge can be calculated once the depth is known e.g. WebMar 5, 2024 · Weirs are commonly used to measure or regulate flow in rivers, streams, irrigation canals, etc. Installing a weir in an open channel system causes critical depth …
WebMar 5, 2024 · Weirs are commonly used to measure or regulate flow in rivers, streams, irrigation canals, etc. Installing a weir in an open channel system causes critical depth to form over the weir. Since there is a unique relationship between the critical depth and discharge, a weir can be designed as a flow-measuring device. ...
