Environmental Discharge is the rate of flow of a liquid through a control section, typically measured in cubic meters per second (m³/s). It represents the volume of fluid passing through a given cross-section per unit time.
The calculator uses the formula:
Where:
Explanation: The formula calculates the discharge by multiplying the cross-sectional area (width × depth) by the velocity of flow at critical conditions.
Details: Accurate discharge calculation is crucial for hydraulic engineering, environmental monitoring, water resource management, and designing fluid transport systems. It helps in assessing flow rates in channels, rivers, and constructed waterways.
Tips: Enter width of throat in meters, critical velocity in meters per second, and critical depth in meters. All values must be positive numbers greater than zero.
Q1: What is Critical Velocity?
A: Critical Velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.
Q2: What is Critical Depth?
A: Critical Depth occurs when the flow in a channel has a minimum specific energy, which refers to the sum of the depth of flow and the velocity head.
Q3: When is this calculation typically used?
A: This calculation is commonly used in hydraulic engineering for designing channels, flumes, and flow measurement devices where critical flow conditions occur.
Q4: What are the limitations of this formula?
A: This formula assumes uniform flow conditions and may not be accurate for non-uniform or rapidly varying flow conditions. It's most accurate for rectangular cross-sections.
Q5: How does throat width affect discharge?
A: Discharge is directly proportional to throat width - doubling the width will double the discharge, assuming velocity and depth remain constant.
