1. What is Flow Rate?

Flow rate is the volume of fluid that passes through a given surface per unit time. It's commonly used in medical settings (IV fluid administration), engineering, and fluid dynamics.

2. How Does the Calculator Work?

The calculator uses the basic flow rate equation:

Where:

• Flow Rate — Measured in mL/s (milliliters per second)
• Volume — Total fluid volume in mL (milliliters)
• Time — Duration in seconds

Explanation: This equation calculates how quickly a volume of fluid is moving or being administered.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation is crucial for proper fluid administration in medical settings, industrial processes, and any application requiring precise fluid control.

4. Using the Calculator

Tips: Enter volume in milliliters and time in seconds. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert to different units?
A: For mL/min, multiply the result by 60. For L/s, divide the result by 1000.

Q2: What's a typical IV flow rate?
A: Typical IV rates range from 20-100 mL/hr, depending on the patient's needs and the medication being administered.

Q3: How does pipe diameter affect flow rate?
A: Flow rate increases with larger pipe diameters when pressure is constant (Poiseuille's Law).

Q4: What's the difference between flow rate and flow velocity?
A: Flow rate is volume per time, while flow velocity is distance per time (speed of the fluid).

Q5: How accurate is this calculation?
A: This provides theoretical flow rate. Actual flow may be affected by viscosity, pressure, and pipe/line resistance.
