1. What is the Water Flow Formula?

The water flow formula (Q = A × v) calculates the volumetric flow rate of water through a pipe or channel. It represents the volume of water passing through a cross-section per unit time.

2. How Does the Calculator Work?

The calculator uses the water flow formula:

Where:

• \( Q \) — Volumetric flow rate (m³/s)
• \( A \) — Cross-sectional area (m²)
• \( v \) — Flow velocity (m/s)

Explanation: The formula calculates how much water volume flows through a given cross-sectional area at a specific velocity per second.

3. Importance of Flow Rate Calculation

Details: Flow rate calculation is essential for designing water supply systems, irrigation systems, hydraulic engineering projects, and monitoring water usage in various applications.

4. Using the Calculator

Tips: Enter cross-sectional area in square meters (m²) and flow velocity in meters per second (m/s). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: Use square meters (m²) for area and meters per second (m/s) for velocity to get flow rate in cubic meters per second (m³/s).

Q2: Can I use different units?
A: Yes, but you'll need to convert your units to maintain consistency. For example, cm² and cm/s would give cm³/s.

Q3: What is a typical flow rate for household water?
A: Typical household water flow rates range from 0.0001 to 0.001 m³/s (0.1-1 L/s) depending on the fixture and water pressure.

Q4: Does this formula work for all fluids?
A: Yes, the formula Q = A × v works for any incompressible fluid, not just water.

Q5: What if the cross-section isn't circular?
A: The formula works for any cross-sectional shape. Just calculate the correct area for that shape (rectangle, ellipse, etc.).
