Total Time & Flow Rate to Total Volume Calculator
This tool will calculate the volume of a fluid flowed over a set period of time at a specified volumetric flow rate.
Introduction
This Total Volume Calculator helps users, technicians, and students quickly determine the total volume of a fluid transferred over a given period of time when the flow rate is known. By entering a flow rate (such as gallons per minute or liters per second) and a time duration (such as minutes or hours), the calculator automatically computes the total volume in the desired units.
This tool is widely used in piping, water distribution, chemical processing, oil & gas, and HVAC applications, where knowing the volume transferred is essential for system design, material balance, and operational efficiency.
Total Time & Flow Rate to Total Volume Calculator
How the Calculator Works
The calculation is based on the fundamental volumetric flow rate formula:
Q = V / t
Symbols
- Q = Volume flow rate
- V = Volume transferred
- t = Time
Example Calculation
Suppose water flows at a rate of 50 liters per minute (L/min) for 2 hours.
Convert time: 2 hours = 120 minutes
Multiply: V = 50 × 120 = 6000 liters
Convert to cubic meters: 6000 ÷ 1000 = 6 m³
So, a pump delivering 50 L/min over 2 hours will transfer 6 cubic meters of water.
Supported Units
This calculator supports multiple flow rate and volume units, including:
Flow rate units: L/min, L/s, m³/hr, gal/min (US & UK), ft³/min
Time units: seconds, minutes, hours, days
Volume units: liters, cubic meters, gallons, cubic feet
Applications of Flow Rate to Volume Conversion
- Water Supply Systems – Estimate how much water is supplied over time
- Pumping Calculations – Determine tank filling or emptying time
- Process Engineering – Track batch volumes in chemical plants
- Oil & Gas – Calculate crude oil or gas transferred in pipelines
- HVAC Systems – Measure chilled water or air volume flow over time
