Frequently Asked Questions
-
What does cubic inch per hour measure?
-
It quantifies volumetric flow rate representing one cubic inch of volume passing a point every hour, especially for very low flow rates.
-
Where is gallon (US) per minute commonly used?
-
It is commonly used in residential and commercial plumbing, HVAC systems, irrigation, and automotive fuel flow measurement.
-
Why are cubic inch/hour values converted to gallons per minute?
-
To translate very low and precise flow rates from laboratory or microfluidic contexts into more practical, larger-scale units relevant to industrial or plumbing applications.
Key Terminology
-
Cubic inch/hour (in^3/h)
-
A unit expressing the volume of one cubic inch passing a cross-section each hour, used for measuring very low flow rates.
-
Gallon (US)/minute (gpm)
-
A volumetric flow unit indicating the number of US liquid gallons flowing per minute.
-
Volumetric Flow Rate
-
The quantity of fluid passing through a cross-section per unit time.
