1. What is LPM?

LPM (Liters Per Minute) is a unit of volumetric flow rate that measures how much liquid volume passes a given point in one minute.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Volume \) — Total liquid volume in liters
• \( Time \) — Duration in minutes

Explanation: The calculation divides the total volume by the time it took for that volume to flow.

3. Importance of Flow Rate Calculation

Details: Flow rate measurements are essential in various applications including medical IV therapy, industrial processes, and water management systems.

4. Using the Calculator

Tips: Enter volume in liters and time in minutes. Both values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between LPM and GPM?
A: LPM measures liters per minute while GPM measures gallons per minute (1 GPM ≈ 3.785 LPM).

Q2: How precise should my measurements be?
A: For medical applications, measure to at least 2 decimal places. For industrial uses, 1 decimal place is often sufficient.

Q3: Can I use this for gases?
A: This calculator is designed for liquids. Gas flow calculations require additional factors like pressure and temperature.

Q4: What are typical LPM values?
A: IV drips might be 0.02-0.1 LPM, while garden hoses might be 10-20 LPM.

Q5: How do I convert LPM to other units?
A: 1 LPM = 0.264 GPM (gallons per minute) = 16.67 mL/sec.
