What Is This Tool?
This converter helps you transform mass flux density values from pound per second per square foot, an imperial unit indicating mass flow rate per area each second, to pound per hour per square foot, which expresses the same measurement over an hourly timeframe.
How to Use This Tool?
-
Enter the mass flux density value in pound/second/square foot into the input field
-
Select pound/second/square foot as the starting unit and pound/hour/square foot as the target unit
-
Click the convert button to see the equivalent value expressed in pounds per hour per square foot
-
Use the result for your engineering or process calculations involving hourly mass flow
Key Features

Browser-based tool requiring no downloads or installations
Examples
-
2 pound/second/square foot converts to approximately 7200 pound/hour/square foot
-
0.5 pound/second/square foot is equivalent to about 1800 pound/hour/square foot
Common Use Cases
-
Quantifying mass flux on fuel injector faces in combustion and propulsion systems
-
Reporting steam or water mass flow rates through heat exchanger tubes in power plants
-
Monitoring particulate or moisture mass loading on HVAC ducts and filters
-
Evaluating condensation or evaporation mass transfer rates on heat exchanger surfaces
Tips & Best Practices
-
Ensure the area unit remains consistent as square foot when applying conversion
-
Use this conversion when expressing mass flux in terms that fit hourly process monitoring
-
Verify steady-state flow conditions to avoid inaccuracies during transient flows
-
Double-check unit selections before converting to prevent errors in calculations
Limitations
-
Rounding the conversion factor may cause precision loss
-
Units assume steady-state conditions; transient flows need more detailed analysis
-
Area units must consistently remain square foot for reliable conversions
Frequently Asked Questions
-
Why convert from pound/second/square foot to pound/hour/square foot?
-
Converting to pound/hour/square foot allows expressing mass flux over longer time intervals suitable for process control and monitoring in engineering applications.
-
Can this conversion be used for transient flow conditions?
-
No, this conversion assumes steady-state flow. Transient flow conditions require more complex analysis beyond this simple unit conversion.
-
Is it important to keep the area unit consistent when converting?
-
Yes, the area must remain in square feet to maintain accuracy and consistency in the mass flux density measurement.
