What is Fluid Ounces per Minute?
Fluid Ounces per minute (fl oz/min) is a unit expressing the volume of fluid that passes a specific point per minute. It's commonly used in contexts where measuring small flow rates is important. It is part of the the Imperial and United States Customary Systems
How is Fluid Ounces per Minute Calculated?
Fluid Ounces per minute is calculated by dividing the volume of fluid (in fluid ounces) by the time it takes for that volume to flow (in minutes).
For example, if 12 fluid ounces of liquid are dispensed in 3 minutes, the flow rate is:
Common Uses and Examples
- IV Drip Rates: In medicine, IV drip rates are often measured in drops per minute, which can be related to fluid ounces per minute. For instance, a doctor might prescribe an IV fluid administration at a rate that equates to a few fluid ounces per hour, necessitating a precise drip rate setting.
- Small Engine Fuel Consumption: The fuel consumption of small engines, like those in lawnmowers or model airplanes, can be measured in fluid ounces per minute. This helps determine the engine's efficiency and fuel requirements.
- 3D Printing: In resin-based 3D printing, the flow rate of resin into the vat can be expressed in fluid ounces per minute, especially for printers with automated resin dispensing systems.
- Beverage Dispensing: Commercial beverage dispensers (soda fountains, juice machines) use fl oz/min to accurately control the amount of liquid dispensed into a cup.
- Laboratory Experiments: Precise fluid delivery in chemical or biological experiments can be crucial, and flow rates are often specified in small units such as fl oz/min or even smaller.
- Water Filtration Systems: Small, point-of-use water filtration systems can have their flow rate specified in fl oz/min, indicating how quickly they can deliver purified water.
Important Considerations
When working with fluid ounces per minute, it is important to distinguish between US fluid ounces and Imperial fluid ounces, as they are slightly different.
- 1 US fluid ounce is approximately 29.57 milliliters.
- 1 Imperial fluid ounce is approximately 28.41 milliliters.

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.
