Mass Flow Rate Conversion

Mass Flow Rate Formula:

\[ W = Q \times \rho \times 60 \]

Mass Flow Rate (lb/hr):

Definition: This calculator converts volumetric flow rate (in gallons per minute) to mass flow rate (in pounds per hour) using fluid density.

Purpose: It helps engineers and technicians in fluid systems to determine mass flow when only volumetric flow is known.

The calculator uses the formula:

\[ W = Q \times \rho \times 60 \]

Where:

Explanation: The volumetric flow is multiplied by density to get mass per minute, then multiplied by 60 to convert to hours.

Details: Mass flow rate is critical for process control, chemical dosing, and energy calculations in fluid systems.

Tips: Enter the volumetric flow rate in GPM and fluid density in lb/gal (default 8.34 for water). All values must be > 0.

Q1: Why convert to mass flow rate?
A: Mass flow is often more useful than volumetric flow for material balance calculations and process control.

Q2: What's the density of water?
A: Water at standard conditions is approximately 8.34 lb/gal.

Q3: Can I use this for gases?
A: No, this calculator is designed for liquids. Gas calculations require different approaches.

Q4: How accurate is this calculation?
A: Accuracy depends on precise density values at operating conditions.

Q5: What if my flow is in different units?
A: Convert to GPM first or modify the formula for your specific units.
