Discharge through Control Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Environmental Discharge - (Measured in Cubic Meter per Second) - Environmental Discharge is the rate of flow of a liquid.
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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Width of Throat: 3 Meter --> 3 Meter No Conversion Required
Critical Velocity: 5.06 Meter per Second --> 5.06 Meter per Second No Conversion Required
Critical Depth: 2.62 Meter --> 2.62 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_e = W_t*V_c*d_c --> 3*5.06*2.62

Evaluating ... ...

Q_e = 39.7716

STEP 3: Convert Result to Output's Unit

39.7716 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

39.7716 Cubic Meter per Second <-- Environmental Discharge

What is Discharge?

The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.

How to Calculate Discharge through Control Section?

Discharge through Control Section calculator uses Environmental Discharge = Width of Throat*Critical Velocity*Critical Depth to calculate the Environmental Discharge, The Discharge through Control Section formula is defined as the measure of the value of the flow of water or other fluids through a specific segment of a hydraulic system, typically where the flow characteristics are well-defined and monitored. Environmental Discharge is denoted by Q_e symbol.

How to calculate Discharge through Control Section using this online calculator? To use this online calculator for Discharge through Control Section, enter Width of Throat (W_t), Critical Velocity (V_c) & Critical Depth (d_c) and hit the calculate button. Here is how the Discharge through Control Section calculation can be explained with given input values -> 39.7716 = 3*5.06*2.62.

FAQ

What is Discharge through Control Section?

The Discharge through Control Section formula is defined as the measure of the value of the flow of water or other fluids through a specific segment of a hydraulic system, typically where the flow characteristics are well-defined and monitored and is represented as Q_e = W_t*V_c*d_c or Environmental Discharge = Width of Throat*Critical Velocity*Critical Depth. Width of Throat is the narrowest section of a conduit or channel, such as in a venturi meter or flume, The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent & 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.

How to calculate Discharge through Control Section?

The Discharge through Control Section formula is defined as the measure of the value of the flow of water or other fluids through a specific segment of a hydraulic system, typically where the flow characteristics are well-defined and monitored is calculated using Environmental Discharge = Width of Throat*Critical Velocity*Critical Depth. To calculate Discharge through Control Section, you need Width of Throat (W_t), Critical Velocity (V_c) & Critical Depth (d_c). With our tool, you need to enter the respective value for Width of Throat, Critical Velocity & Critical Depth and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Environmental Discharge?

In this formula, Environmental Discharge uses Width of Throat, Critical Velocity & Critical Depth. We can use 3 other way(s) to calculate the same, which is/are as follows -
