AquaCalc Exercise

Scenario:

You are a water resource engineer tasked with evaluating the flow rate of a river using a weir. You collect the following data:

• Weir crest height (H): 0.5 meters
• Head (h): 0.2 meters
• Weir coefficient (Cd): 0.6

Task:

Using the following equation, calculate the flow rate (Q) in cubic meters per second (m³/s) using AquaCalc's flow calculation feature.

Equation:

Q = Cd * (2g)^(1/2) * H^(3/2) * h^(1/2)

Where:

• g = acceleration due to gravity (9.81 m/s²)

Instructions:

1. Import the data into AquaCalc.
2. Select the appropriate flow calculation method (weir).
3. Input the necessary parameters (H, h, Cd, g).
4. Calculate the flow rate (Q).

AquaCalc: A Powerful Tool for Open Channel Flow Measurement in Environmental & Water Treatment

Chapter 1: Techniques

Open Channel Flow Measurement Techniques

This chapter explores the various techniques employed for measuring flow in open channels, which form the foundation for AquaCalc's functionalities.

• Weirs: These structures create a predictable head-discharge relationship by obstructing flow, allowing for flow calculation based on the height of the water above the weir crest.
  • Types of Weirs:
    • Rectangular weirs
    • Triangular weirs
    • Cipolletti weirs
    • Broad-crested weirs

  • Types of Flumes:
    • Parshall flumes
    • Venturi flumes
    • Rectangular flumes
    • H-flumes
• Ultrasonic Flow Meters: Non-invasive devices that utilize the travel time of sound waves through the water to measure flow velocity and ultimately calculate flow.
• Doppler Flow Meters: These instruments rely on the Doppler effect, measuring the frequency shift of sound waves reflected from moving water particles to determine flow velocity.
