1. What is GPM to kg/hr Conversion?

The GPM to kg/hr conversion calculates the mass flow rate of water in kilograms per hour based on the volumetric flow rate in gallons per minute. This conversion is essential for engineering calculations involving fluid dynamics and mass balance.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

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

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

3. Importance of Flow Rate Conversion

Details: Converting volumetric flow rate to mass flow rate is crucial for chemical engineering processes, water treatment systems, hydraulic calculations, and energy balance equations where mass conservation is required.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The calculator will automatically compute the equivalent mass flow rate in kilograms per hour for water.

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 at standard conditions. For other fluids, use the appropriate density conversion.

Q2: What is the derivation of the conversion factor?
A: 1 GPM × 8.345 lb/gal (water density) × 0.4536 kg/lb × 60 min/hour = 226.796 kg/hr.

Q3: When is this conversion typically used?
A: Commonly used in plumbing, irrigation systems, chemical processing, and any application involving water flow rate measurements.

Q4: How accurate is this conversion?
A: The conversion is accurate for water at standard temperature and pressure (20°C, 1 atm). Density changes with temperature should be considered for precise calculations.

Q5: Can this be used for other liquids?
A: For other liquids, multiply the result by the specific gravity (density relative to water) of the liquid.
