1. What is a Volumetric Flow Rate to Volume Calculator?

Definition: This calculator converts flow rate (in gallons per minute) and time into total volume (in cubic feet).

Purpose: It helps engineers, plumbers, and fluid system designers determine the total volume of fluid that passes through a system over a given time period.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_t = Q \times t \times 7.481 \]

Where:

Explanation: The flow rate is multiplied by time to get gallons, then converted to cubic feet (since 1 ft³ = 7.481 gallons).

3. Importance of Flow Rate to Volume Conversion

Details: This calculation is essential for system design, tank sizing, process control, and verifying flow meter accuracy.

4. Using the Calculator

Tips: Enter the flow rate in GPM and time in minutes. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 7.481?
A: This converts gallons to cubic feet (1 cubic foot = 7.481 gallons).

Q2: Can I use this for other time units?
A: The calculator expects minutes. For hours, multiply by 60 before entering.

Q3: What's a typical flow rate for household plumbing?
A: Standard faucets flow about 2-3 GPM, showers 1.5-2.5 GPM.

Q4: How accurate is this calculation?
A: It's mathematically precise assuming constant flow rate.

Q5: Can I calculate time if I know volume and flow rate?
A: Yes, rearrange the formula: t = V_t / (Q × 7.481)
