What Is This Tool?
This unit converter transforms measurements of mass flux density from pounds per hour per square foot to kilograms per hour per square meter, facilitating the comparison and reporting of mass flow rates across different measurement systems used in scientific and engineering fields.
How to Use This Tool?
-
Enter the value in pound/hour/square foot that you want to convert.
-
Select 'pound/hour/square foot' as the input unit.
-
Choose 'kilogram/hour/square meter' as the output unit.
-
Perform the conversion to get the equivalent mass flux density in kilograms per hour per square meter.
Key Features
-
Converts mass flux density between imperial and metric units.
-
Based on the defined conversion factor: 1 pound/hour/square foot equals 4.882427687 kilogram/hour/square meter.
-
Useful for various industries including power plants, HVAC, chemical engineering, hydrology, and meteorology.
Examples
-
2 pound/hour/square foot converts to 9.764855374 kilogram/hour/square meter.
-
0.5 pound/hour/square foot converts to 2.441213844 kilogram/hour/square meter.
Common Use Cases
-
Specifying steam or water mass flux in power and process plants through boiler or heat-exchanger tubes.
-
Reporting air or particulate mass flux in HVAC systems and environmental control.
-
Measuring precipitation or evaporation rates in hydrology and meteorology.
-
Calculating membrane permeate or reject flux in chemical engineering processes.
-
Assessing deposition or coating rates in industrial or aerosol applications.
Tips & Best Practices
-
Ensure consistent and uniform measurement conditions for accurate conversions.
-
Be aware of unit differences in surface area impact when interpreting results.
-
Use the conversion for reconciling data between imperial and metric unit systems.
Limitations
-
Conversion assumes steady and uniform mass flow across the area considered.
-
Does not account for variations in temperature or pressure that can influence mass flux.
-
Accuracy depends on precise measurement and definition of square foot and square meter areas.
Frequently Asked Questions
-
What does pound/hour/square foot measure?
-
It measures the mass flux density as the mass in pounds flowing through one square foot of area per hour.
-
Why convert to kilogram/hour/square meter?
-
Converting to kilogram/hour/square meter allows comparison and reporting in the metric system, widely used in scientific and engineering contexts.
-
Can this converter be used for varying temperature or pressure conditions?
-
No, the conversion assumes uniform conditions and does not adjust for changes in temperature or pressure.
Key Terminology
-
Mass Flux Density
-
The amount of mass that passes through or is transferred over a unit area per unit of time.
-
Pound/hour/square foot
-
An imperial unit measuring mass flux density as pounds of mass passing through one square foot per hour.
-
Kilogram/hour/square meter
-
A metric unit for mass flux density indicating kilograms of mass crossing or accumulating on one square meter each hour.
