1. What is GPM to kg/hr Conversion?

The GPM to kg/hr conversion is used to convert flow rate from gallons per minute to kilograms per hour for water. This conversion is essential in various engineering and industrial applications where flow rates need to be expressed in different units.

2. How Does the Converter Work?

The converter uses the following formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 226.796 \) — Conversion factor (based on water density)
• \( kg/hr \) — Flow rate in kilograms per hour

Explanation: The conversion factor 226.796 is derived from the density of water (1 gallon of water ≈ 3.78541 kg) and the time conversion (60 minutes in 1 hour).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering calculations, process design, equipment sizing, and system optimization in water treatment, chemical processing, and HVAC systems.

4. Using the Converter

Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The converter will automatically calculate the equivalent flow rate in kilograms per hour (kg/hr).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 226.796?
A: The factor comes from 3.78541 kg/gallon × 60 minutes/hour = 226.796 kg·min/(gallon·hr).

Q2: Does this conversion work for fluids other than water?
A: No, this conversion is specific to water. For other fluids, you need to multiply by the specific density of that fluid.

Q3: What are typical GPM values in practical applications?
A: Residential water systems: 5-15 GPM, industrial processes: 50-500 GPM, large municipal systems: 1000+ GPM.

Q4: When is kg/hr preferred over GPM?
A: kg/hr is commonly used in mass balance calculations, chemical processes, and international engineering standards where metric units are required.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact for water at standard conditions. Actual values may vary slightly with temperature and water purity.
