Width of Throat given Discharge through Control Section Formula Elements

Variables
Width of Throat
Width of Throat is the narrowest section of a conduit or channel, such as in a venturi meter or flume.
Symbol: Wt
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Environmental Discharge
Environmental Discharge is the rate of flow of a liquid.
Symbol: Qe
Measurement: Volumetric Flow RateUnit: m³/s
Note: Value should be greater than 0.
Critical Depth
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.
Symbol: dc
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Critical Velocity
The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.
Symbol: Vc
Measurement: SpeedUnit: m/s
Note: Value can be positive or negative.
