1. What is the Flow Addition Equation?

The flow addition equation calculates the total flow rate when two water streams are combined. It's based on the principle of conservation of mass in fluid dynamics.

2. How Does the Calculator Work?

The calculator uses the flow addition equation:

Where:

• \( Flow_1 \) — Flow rate of first stream (l/s)
• \( Flow_2 \) — Flow rate of second stream (l/s)
• \( Flow_{total} \) — Combined flow rate (l/s)

Explanation: When two water streams mix, their flow rates add together linearly assuming complete mixing and no losses.

3. Importance of Flow Calculation

Details: Accurate flow calculation is essential for designing water distribution systems, irrigation systems, and industrial processes where multiple water sources combine.

4. Using the Calculator

Tips: Enter both flow rates in liters per second (l/s). All values must be non-negative. The calculator will sum the two flows.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for different units?
A: The calculator uses l/s (liters per second). Convert all flows to the same unit before calculation.

Q2: What if the flows have different temperatures?
A: This calculator only sums flow rates. Temperature mixing requires additional calculations.

Q3: Is this valid for turbulent mixing?
A: Yes, the flow rate summation is valid regardless of mixing conditions, though complete mixing may require sufficient distance downstream.

Q4: Can I add more than two flows?
A: The principle extends to multiple flows: Flow_total = Flow₁ + Flow₂ + ... + Flow_n

Q5: What about pressure changes?
A: Pressure effects aren't considered in this simple flow addition. System pressure calculations require hydraulic analysis.
