1. What is the Flow Rate Equation?

The flow rate equation (Q = V/t) calculates the volumetric flow rate of a fluid by dividing the volume of fluid that passes through a given surface by the time taken.

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 the direct relationship between volume and flow rate, and the inverse relationship between time and flow rate.

3. Importance of Flow Rate Calculation

Details: Flow rate calculations are essential in fluid dynamics, engineering, plumbing, and many industrial processes where controlling fluid movement is critical.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common units for flow rate?
A: Common units include m³/s, L/s, mL/min, and gallons per minute (GPM), depending on the application.

Q2: How does pipe diameter affect flow rate?
A: For a given velocity, flow rate increases with the square of the pipe diameter (Q = v × A, where A is cross-sectional area).

Q3: What's the difference between volumetric and mass flow rate?
A: Volumetric flow rate measures volume per time, while mass flow rate measures mass per time (related by fluid density).

Q4: When is this equation not applicable?
A: For compressible fluids at high velocities or when significant pressure/temperature changes occur, more complex equations are needed.

Q5: How can I measure flow rate experimentally?
A: Common methods include flow meters, timed volume collection, or using the continuity equation with known velocities and cross-sections.
