1. What is GPM to kg/h Conversion?

The GPM to kg/h conversion calculates 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 Calculator Work?

The calculator uses the conversion formula:

Where:

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

Explanation: The conversion factor 226.796 is derived from the density of water (1 kg/L ≈ 8.345 lb/gal) and time conversion (60 minutes/hour).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for hydraulic calculations, pump sizing, process engineering, and system design where different units are used in various standards and specifications.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator assumes water as the fluid at standard conditions.

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion specific to water?
A: Yes, the conversion factor 226.796 is based on the density of water. For other fluids, different conversion factors apply based on their specific density.

Q2: What is the accuracy of this conversion?
A: The conversion is accurate for water at standard conditions (4°C). For precise engineering applications, temperature and pressure corrections may be needed.

Q3: Can this be used for any liquid?
A: No, this conversion is specifically for water. For other liquids, multiply the result by the specific gravity of the liquid relative to water.

Q4: What are typical GPM values in practice?
A: Residential water systems: 5-15 GPM, industrial processes: 50-500 GPM, large municipal systems: 1000+ GPM.

Q5: Why convert to kg/h?
A: kg/h is commonly used in mass flow calculations, chemical processes, and international standards where metric units are preferred.
