1. What is a Specific Volume to Mass Flow Rate Calculator?

Definition: This calculator converts volumetric flow rate to mass flow rate using the fluid's specific volume.

Purpose: It helps engineers and technicians determine mass flow rates in fluid systems when working with volumetric measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \frac{Q}{v \times 60} \]

Where:

Explanation: The volumetric flow rate is divided by the product of specific volume and 60 (to convert minutes to hours) to obtain mass flow rate.

3. Importance of Mass Flow Rate Calculation

Details: Accurate mass flow rate determination is crucial for system design, process control, and energy calculations in fluid systems.

4. Using the Calculator

Tips: Enter the volumetric flow rate in GPM and specific volume in gal/lb (default 0.016 for water at room temperature). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is specific volume?
A: Specific volume is the volume occupied by a unit mass of a substance (reciprocal of density).

Q2: Why is 60 included in the formula?
A: The factor of 60 converts minutes (from GPM) to hours (for lb/hr).

Q3: What's a typical specific volume for water?
A: Water at room temperature has a specific volume of about 0.016 gal/lb (or 0.016 ft³/lb).

Q4: How do I find specific volume for other fluids?
A: Consult thermodynamic property tables or use the reciprocal of the fluid's density.

Q5: Can I use this for gases?
A: Yes, but ensure units are consistent and account for compressibility effects at high pressures.
