1. What is Flow Rate Per Hour?

Flow rate per hour measures the volume of liquid that passes through a given point in a system per unit time (hour). It's commonly used in medical, engineering, and industrial applications.

2. How Does the Calculator Work?

The calculator uses the flow rate equation:

Where:

• \( Q \) — Flow rate (litres/hour)
• \( V \) — Volume (litres)
• \( t \) — Time (hours)

Explanation: The equation simply divides the total volume by the time period to determine the flow rate per hour.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation is essential for IV fluid administration, industrial processes, water treatment systems, and many other applications where precise liquid delivery is required.

4. Using the Calculator

Tips: Enter volume in litres and time in hours. All values must be valid (volume > 0, time > 0). The calculator will compute the flow rate in litres per hour.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: This calculator specifically uses litres for volume and hours for time. Convert your measurements to these units before calculation.

Q2: What's a typical flow rate for IV fluids?
A: IV flow rates vary by patient need but typically range from 20-100 mL/hour for maintenance fluids to much higher rates for rapid resuscitation.

Q3: How do I calculate flow rate for minutes instead of hours?
A: First calculate litres/hour, then divide by 60 to get litres/minute. Or convert your time measurement to hours (minutes/60) before calculation.

Q4: What factors can affect flow rate accuracy?
A: Tube diameter, liquid viscosity, pressure, and obstructions can all affect actual flow rates in physical systems.

Q5: Is this calculator suitable for gas flow rates?
A: This calculator is designed for liquids. Gas flow calculations require additional factors like pressure and temperature.
