Let's explore the conversion between cubic inches per minute (in³/min) and centilitres per second (cL/s).
Understanding Volume Flow Rate Conversion
Converting between different units of volume flow rate involves understanding the relationships between the individual units of volume and time. In this case, we need to know how cubic inches relate to centilitres, and how minutes relate to seconds
Conversion Factors
- 1 cubic inch () = 16.387064 centilitres (cL) [Source: NIST Handbook 44]
- 1 minute = 60 seconds
Converting Cubic Inches per Minute to Centilitres per Second
To convert from cubic inches per minute to centilitres per second, we use the following steps:
- Convert cubic inches to centilitres: Multiply the value in cubic inches by 16.387064 to get the equivalent value in centilitres.
- Convert minutes to seconds: Divide by 60 to convert from per minute to per second.
Combining these steps into a single formula:
Example: Convert 1 cubic inch per minute to centilitres per second
Therefore, 1 cubic inch per minute is approximately equal to 0.2731 centilitres per second.
Converting Centilitres per Second to Cubic Inches per Minute
To convert from centilitres per second to cubic inches per minute, we reverse the process:
- Convert centilitres to cubic inches: Divide the value in centilitres by 16.387064 to get the equivalent value in cubic inches.

What is cubic inches per minute?
What is Cubic Inches per Minute?
Cubic inches per minute (in$^3$/min or CFM) is a unit of measure for volume flow rate. It represents the volume of a substance (typically a gas or liquid) that flows through a given area per minute, with the volume measured in cubic inches. It's a common unit in engineering and manufacturing, especially in the United States.
Understanding Cubic Inches and Volume Flow Rate
Cubic Inches
A cubic inch is a unit of volume equal to the volume of a cube with sides one inch long. It's part of the imperial system of measurement.
Volume Flow Rate
Volume flow rate, generally denoted as , is the volume of fluid which passes per unit time. The SI unit for volume flow rate is cubic meters per second ().
Formation of Cubic Inches per Minute
Cubic inches per minute is formed by combining a unit of volume (cubic inches) with a unit of time (minutes). This describes how many cubic inches of a substance pass a specific point or through a specific area in one minute.
Where:
- = Volume flow rate (in$^3$/min)
- = Volume (in$^3$)
- = Time (min)
Applications and Examples
Cubic inches per minute is used across various industries. Here are some real-world examples:
- Automotive: Measuring the air intake of an engine or the flow rate of fuel injectors. For instance, a fuel injector might have a flow rate of 100 in$^3$/min.
- HVAC (Heating, Ventilation, and Air Conditioning): Specifying the airflow capacity of fans and blowers. A small bathroom fan might move air at a rate of 50 in$^3$/min.
- Pneumatics: Determining the flow rate of compressed air in pneumatic systems. An air compressor might deliver 500 in$^3$/min of air.
- Manufacturing: Measuring the flow of liquids in industrial processes, such as coolant flow in machining operations. A coolant pump might have a flow rate of 200 in$^3$/min.
- 3D Printing: When using liquid resins.
Conversions and Related Units
It's important to understand how cubic inches per minute relates to other units of flow rate:
- Cubic Feet per Minute (CFM): 1 CFM = 1728 in$^3$/min
- Liters per Minute (LPM): 1 in$^3$/min ≈ 0.01639 LPM
- Gallons per Minute (GPM): 1 GPM ≈ 231 in$^3$/min
Interesting Facts
While there's no specific law directly associated with cubic inches per minute itself, the underlying principles of fluid dynamics that govern volume flow rate are described by fundamental laws such as the Navier-Stokes equations. These equations, developed in the 19th century, describe the motion of viscous fluids and are essential for understanding fluid flow in a wide range of applications. For more information you can read about it in the following Navier-Stokes Equations page from NASA.
What is centilitres per second?
Centilitres per second (cL/s) is a unit used to measure volume flow rate, indicating the volume of fluid that passes a given point per unit of time. It's a relatively small unit, often used when dealing with precise or low-volume flows.
Understanding Centilitres per Second
Centilitres per second expresses how many centilitres (cL) of a substance move past a specific location in one second. Since 1 litre is equal to 100 centilitres, and a litre is a unit of volume, centilitres per second is derived from volume divided by time.
- 1 litre (L) = 100 centilitres (cL)
- 1 cL = 0.01 L
Therefore, 1 cL/s is equivalent to 0.01 litres per second.
Calculation of Volume Flow Rate
Volume flow rate () can be calculated using the following formula:
Where:
- = Volume flow rate
- = Volume (in centilitres)
- = Time (in seconds)
Alternatively, if you know the cross-sectional area () through which the fluid is flowing and its average velocity (), the volume flow rate can also be calculated as:
Where:
- = Volume flow rate (in cL/s if A is in and is in cm/s)
- = Cross-sectional area
- = Average velocity
For a deeper dive into fluid dynamics and flow rate, resources like Khan Academy's Fluid Mechanics section provide valuable insights.
Real-World Examples
While centilitres per second may not be the most common unit in everyday conversation, it finds applications in specific scenarios:
-
Medical Infusion: Intravenous (IV) drips often deliver fluids at rates measured in millilitres per hour or, equivalently, a fraction of a centilitre per second. For example, delivering 500 mL of saline solution over 4 hours equates to approximately 0.035 cL/s.
-
Laboratory Experiments: Precise fluid dispensing in chemical or biological experiments might involve flow rates measured in cL/s, particularly when using microfluidic devices.
-
Small Engine Fuel Consumption: The fuel consumption of very small engines, like those in model airplanes or some specialized equipment, could be characterized using cL/s.
-
Dosing Pumps: The flow rate of dosing pumps could be measured in centilitres per second.
Associated Laws and People
While there isn't a specific law or well-known person directly associated solely with the unit "centilitres per second," the underlying principles of fluid dynamics and flow rate are governed by various laws and principles, often attributed to:
- Blaise Pascal: Pascal's Law is fundamental to understanding pressure in fluids.
- Daniel Bernoulli: Bernoulli's principle relates fluid speed to pressure.
- Osborne Reynolds: The Reynolds number is used to predict flow patterns, whether laminar or turbulent.
These figures and their contributions have significantly advanced the study of fluid mechanics, providing the foundation for understanding and quantifying flow rates, regardless of the specific units used.
