What Is This Tool?
This converter allows users to translate a volumetric flow rate measured in gallon (UK)/second into a mass flow rate expressed as kilogram/day for gasoline at a standardized temperature of 15.5°C. It facilitates accurate flow rate conversions crucial for petroleum custody transfer and inventory management.
How to Use This Tool?
-
Enter the flow rate value in gallon (UK)/second
-
Select gallon (UK)/second as the input unit and kilogram/day (Gasoline at 15.5°C) as the output unit
-
Initiate the conversion to get the corresponding mass flow rate
-
Use the output for custody transfer, process calculations, or inventory reporting
Key Features
-
Converts gallon (UK)/second volumetric flow to kilogram/day mass flow standardized to gasoline at 15.5°C
-
Supports applications involving imperial (UK) gallon flow measurements
-
Ideal for custody transfer, fuel delivery invoicing, and refinery process monitoring
-
Shows example calculations for clear understanding
-
Provides definitions and context for each unit involved
Examples
-
Converting 2 gallon (UK)/second gives 580790.55120786 kilogram/day (Gasoline at 15.5°C)
-
Converting 0.5 gallon (UK)/second results in 145197.637801965 kilogram/day (Gasoline at 15.5°C)
Common Use Cases
-
Specifying pump or meter capacities in systems using imperial (UK) units
-
Reporting transient water supply flows or hydrant testing with imperial gallons
-
Custody transfer and invoicing for gasoline transported by pipeline or tanker
-
Inventory reconciliation at fuel depots and refineries
-
Calculating fuel consumption and emissions in refining operations
Tips & Best Practices
-
Ensure gasoline temperature is referenced at 15.5°C for accurate mass conversions
-
Use this conversion only for gasoline due to specific density at 15.5°C
-
Verify units carefully to distinguish imperial gallon from other gallon types
-
Apply mass flow results to custody transfer and inventory systems for accuracy
-
Double-check input values for consistency with system measurement units
Limitations
-
Accuracy depends on gasoline density precisely at 15.5°C; temperature variations affect results
-
Conversion applies solely to gasoline; other fluids require different density considerations
-
The gallon unit refers specifically to the imperial (UK) gallon, not other gallon definitions
Frequently Asked Questions
-
Why is gasoline density referenced at 15.5°C for this conversion?
-
The 15.5°C reference temperature standardizes mass–volume conversions for custody transfer and inventory, compensating for temperature-related density changes.
-
Can I use this converter for fluids other than gasoline?
-
No, this conversion specifically applies to gasoline density at 15.5°C; other fluids require adjustments according to their densities.
-
What is the difference between gallon (UK) and other gallon units?
-
The gallon (UK) is an imperial unit equal to 4.54609 litres, different from US liquid gallons; conversions are valid only for imperial gallons.
Key Terminology
-
Gallon (UK)/second
-
A volumetric flow rate representing one imperial gallon (4.54609 litres) of fluid passing per second.
-
Kilogram/day (Gasoline at 15.5°C)
-
A mass flow rate specifying the mass of gasoline passing a point each day, standardized by density at 15.5°C.
-
Custody Transfer
-
The process of transferring ownership of petroleum products where accurate volume and mass measurements are critical.
