Flow Rate Formula:
From: | To: |
Definition: This calculator determines the outflow rate from a tank based on the volume of liquid and the time it takes to empty.
Purpose: It helps engineers, plumbers, and facility managers calculate flow rates for system design, maintenance, and troubleshooting.
The calculator uses the formula:
Where:
Explanation: The volume is divided by time to determine the average flow rate during the emptying process.
Details: Accurate flow rate calculations ensure proper system design, help diagnose problems, and verify pump performance.
Tips: Enter the tank volume in gallons and the time it takes to empty in minutes. Both values must be > 0.
Q1: What units does this calculator use?
A: The calculator uses gallons for volume and minutes for time, resulting in gallons per minute (gpm).
Q2: Can I use this for other liquids besides water?
A: Yes, as long as the volume is measured in gallons, it works for any liquid.
Q3: Does this calculate instantaneous or average flow rate?
A: This calculates the average flow rate over the entire emptying period.
Q4: How accurate is this calculation?
A: It provides a theoretical average. Actual rates may vary due to factors like pipe friction, elevation changes, and valve settings.
Q5: What if my tank isn't completely emptying?
A: Use the actual volume discharged (not the full tank capacity) and the time it took to discharge that volume.
