17 апр. 2023 г. · 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 ...

The critical depth, denoted by yc, is the flow depth at a section where the flow is critical. In a given open channel, the critical flow may not occur at all.

8 апр. 2019 г. · It acts as a datum from which your measured depths can be compared to. This tells you whether the flow is subcritical or super critical.

Critical depth occurs when the flow in a channel has a minimum specific energy. Specific energy refers to the sum of the depth of flow and the velocity head.

19 июл. 2022 г. · Critical depth of flow is that of flow at which the specific energy is minimum. From the above graph, it is the depth of flow at point 'C'.

Critical depth is also the depth of maximum discharge, when the specific energy is held constant. Froude Number: The Froude number is an important dimensionless ...

The exception is at critical flow conditions, where only one depth exists, the critical depth. Which of these depths is exhibited by the flow is determined by ...

7 авг. 2021 г. · The critical depth (yc) is the normal depth at critical flow conditions for a given flow rate in a given channel (ie given channel bottom slope, Manning ...

Critical depth is a quantity of fundamental importance to understanding the flow characteristics. If the actual depth is greater than critical depth, then the ...
