-
Assumes steady flow and does not incorporate transient or variable flow conditions
-
May not reflect actual variations in flow during pulsatile or intermittent operations
Frequently Asked Questions
-
Why convert cubic foot/hour to cubic foot/second?
-
Converting allows flow rates measured over an hour to be expressed on a per-second basis, which is common in hydrology and high-speed process applications.
-
What is the conversion rate between ft³/h and ft³/s?
-
The conversion involves multiplying cubic foot per hour by 0.0002777778 to obtain the equivalent cubic foot per second.
-
Can this conversion be used for pulsatile flows?
-
No, the conversion assumes steady flow conditions and does not account for flows that vary within the measurement period.
Key Terminology
-
Cubic foot/hour [ft^3/h]
-
A volumetric flow rate unit measuring one cubic foot of fluid passing a point in one hour.
-
Cubic foot/second [ft^3/s]
-
A volumetric flow rate unit representing one cubic foot of fluid passing a point each second, commonly used in hydrology and engineering.
-
Volumetric Flow Rate
-
The quantity of fluid that passes through a given surface per unit time.
