Width of Throat given Discharge through Control Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

Width of Throat = (Environmental Discharge/(Critical Depth*Critical Velocity))
W_t = (Q_e/(d_c*V_c))
This formula uses 4 Variables

Variables Used

Width of Throat - (Measured in Meter) - Width of Throat is the narrowest section of a conduit or channel, such as in a venturi meter or flume.
Environmental Discharge - (Measured in Cubic Meter per Second) - Environmental Discharge is the rate of flow of a liquid.
Critical Depth - (Measured in Meter) - 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.
Critical Velocity - (Measured in Meter per Second) - The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.

STEP 1: Convert Input(s) to Base Unit

Environmental Discharge: 39.82 Cubic Meter per Second --> 39.82 Cubic Meter per Second No Conversion Required
Critical Depth: 2.62 Meter --> 2.62 Meter No Conversion Required
Critical Velocity: 5.06 Meter per Second --> 5.06 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_t = (Q_e/(d_c*V_c)) --> (39.82/(2.62*5.06))

Evaluating ... ...

W_t = 3.00365084633256

STEP 3: Convert Result to Output's Unit

3.00365084633256 Meter --> No Conversion Required

FINAL ANSWER

3.00365084633256 ≈ 3.003651 Meter <-- Width of Throat

What is Critical Velocity?

The velocity at which flow transitions from being subcritical to supercritical. In open channel flow, critical velocity occurs when the flow's kinetic energy is equal to the potential energy. It's a point where the flow is neither too fast nor too slow, and it determines the efficiency and behavior of the channel.
