What is cubic inches per hour?
Cubic inches per hour is a unit of volume flow rate. The following sections describe cubic inches per hour in more detail.
Understanding Cubic Inches per Hour
Cubic inches per hour (in$^3$/hr) is a unit used to measure the volume of a substance (liquid or gas) that flows past a certain point in a specific amount of time. It indicates how many cubic inches of a substance move within one hour.
Formation of Cubic Inches per Hour
This unit is derived from two base units:
- Cubic inch (in$^3$): A unit of volume. It represents the volume of a cube with sides of 1 inch each.
- Hour (hr): A unit of time.
The unit is formed by dividing a volume expressed in cubic inches by a time expressed in hours, resulting in a rate of flow:
Applications of Cubic Inches per Hour
Cubic inches per hour is practically used in real-world applications where the measurement of slow, very small volume flow rate is important. The SI unit for Volume flow rate is . Some examples are:
- Small Engine Fuel Consumption: Measuring the fuel consumption of small engines, such as those in lawnmowers or model airplanes.
- Medical Devices: Infusion pumps may use this unit to measure how slowly medicine flows into the patient.
- Hydraulics: Very small scale of hydraulic flow, where precision is needed.
- 3D Printing: Material extrusion volume in 3D printing, particularly for small-scale or intricate designs.
Conversion to Other Units
Cubic inches per hour can be converted to other units of volume flow rate, such as:
- Cubic feet per hour (ft$^3$/hr)
- Gallons per hour (gal/hr)
- Liters per hour (L/hr)
- Cubic meters per second (m$^3$/s)
Flow Rate
Flow rate, generally speaking, plays an important role in many different areas of science and engineering. For example, cardiovascular system uses the concept of flow rate to determine blood flow.

What is Cubic feet per hour?
Cubic feet per hour (CFH) is a unit used to measure the volumetric flow rate. It represents the volume of a substance (gas or liquid) that passes through a specific area per hour, measured in cubic feet. It's a common unit in various fields, especially when dealing with gas and air flow.
Definition of Cubic Feet per Hour
Cubic feet per hour (CFH) is defined as the volume of a substance, measured in cubic feet, that flows past a point in one hour.
How CFH is Formed
CFH is derived from the basic units of volume (cubic feet) and time (hour). It directly expresses how many cubic feet of a substance move within one hour. No special law or constant is specifically tied to the definition of CFH itself. It is a direct measure of flow rate, useful in practical applications.
Calculating Volume Flow Rate
The volume flow rate (Q) in cubic feet per hour can be determined using the following formula:
Where:
- = Volume flow rate (ft³/hour)
- = Cross-sectional area of the flow (ft²)
- = Average velocity of the flow (ft/hour)
Another way to calculate it is:
Where:
- = Volume flow rate (ft³/hour)
- = Volume (ft³)
- = Time (hours)
Real-World Examples of CFH
- Natural Gas Consumption: Home appliances like furnaces, water heaters, and stoves are rated in terms of CFH to indicate their natural gas consumption. A typical furnace might consume 80-120 CFH of natural gas.
- HVAC Systems: Air conditioning and ventilation systems use CFH to measure the airflow rate in ductwork. A residential HVAC system might require airflow rates between 400 and 1600 CFH, depending on the size of the home.
- Compressed Air Systems: Pneumatic tools and equipment in factories use compressed air. The compressor output is often rated in CFH or cubic feet per minute (CFM, which can easily be converted to CFH by multiplying by 60) to indicate the volume of air it can supply.
- Industrial Processes: Many industrial processes, such as chemical manufacturing or food processing, involve controlling the flow rate of liquids or gases. CFH can be used to specify the desired flow rate of a particular fluid. For example, a chemical reactor might require a flow of 50 CFH of nitrogen gas.
- Ventilation Systems: Exhaust fans in bathrooms or kitchens are often rated in CFM (cubic feet per minute), which can be converted to CFH. A typical bathroom exhaust fan might be rated at 50-100 CFM, which equals 3000-6000 CFH.
Frequently Asked Questions
What is the formula to convert Cubic inches per hour to Cubic feet per hour?
To convert Cubic inches per hour to Cubic feet per hour, multiply the flow rate in by the verified factor . The formula is: . This gives the equivalent volume flow rate in Cubic feet per hour.
