1. What is the Flow Rate Equation?

The flow rate equation (Q = V/t) calculates the volume of fluid passing through a given surface per unit time. It's fundamental in fluid dynamics and engineering applications.

2. How Does the Calculator Work?

The calculator uses the flow rate equation:

Where:

• \( Q \) — Flow rate (m³/s)
• \( V \) — Volume (m³)
• \( t \) — Time (s)

Explanation: The equation shows that flow rate is directly proportional to volume and inversely proportional to time.

3. Importance of Flow Rate Calculation

Details: Flow rate calculations are essential in designing piping systems, water supply networks, chemical processing, and many engineering applications where fluid movement is involved.

4. Using the Calculator

Tips: Enter volume in cubic meters (m³) and time in seconds (s). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for flow rate?
A: While m³/s is standard, other common units include liters/second, gallons/minute, and cubic feet/hour depending on the application.

Q2: How does flow rate relate to velocity?
A: Flow rate equals cross-sectional area multiplied by average velocity (Q = A × v).

Q3: What's the difference between mass flow rate and volumetric flow rate?
A: Volumetric flow rate (Q) measures volume per time, while mass flow rate (ṁ) measures mass per time (ṁ = ρQ, where ρ is density).

Q4: When is this equation not applicable?
A: For compressible fluids at high velocities or when dealing with non-Newtonian fluids, more complex equations may be needed.

Q5: How can I measure flow rate experimentally?
A: Common methods include flow meters, measuring collection time for known volumes, or using the continuity equation with known cross-sections.
