What is millilitres per second?
Millilitres per second (mL/s) is a unit of volumetric flow rate, describing the volume of fluid that passes through a given point per unit of time. It's commonly used in various fields where precise measurement of small fluid volumes is essential.
Definition of Millilitres per Second
Millilitres per second (mL/s) is a derived unit. It combines the metric unit of volume, the milliliter (mL), with the SI unit of time, the second (s). One milliliter is equal to one cubic centimeter (). Therefore, 1 mL/s is equivalent to 1 cubic centimeter of fluid flowing past a point in one second.
How Millilitres per Second is Formed
The unit is formed by expressing volume in milliliters and dividing it by time in seconds.
Common Applications and Examples
- Medical Applications: Infusion pumps deliver medication at precise rates, often measured in mL/s. For instance, a doctor might prescribe an IV drip at a rate of 0.5 mL/s.
- Laboratory Experiments: Chemical reactions and experiments often require precise control over the flow of liquids. Microfluidic devices frequently operate in the mL/s range or even lower.
- Small Engine Fuel Consumption: The fuel consumption of a small engine, like a lawnmower, can be expressed in mL/s. For example, an engine might consume 2 mL/s of gasoline at idle.
- 3D Printing: In material extrusion 3D printing, the flow rate of the melted filament is often controlled and can be expressed in mL/s.
- Water flow from faucets: A slowly dripping faucet might release water at a rate of approximately 0.1 mL/s. A fully open faucet might release water at a rate of 200 mL/s.
Relationship to Other Units
Millilitres per second can be converted to other volumetric flow rate units:
- Liters per second (L/s): 1 L/s = 1000 mL/s
- Cubic meters per second (): 1 = 1,000,000 mL/s
- Gallons per minute (GPM): 1 GPM ≈ 0.0630902 L/s ≈ 63.0902 mL/s
Notable Figures and Laws
While no specific law is directly associated with milliliters per second, the concept of flow rate is fundamental in fluid dynamics. Key figures in this field include:
- Daniel Bernoulli: Known for Bernoulli's principle, which relates fluid speed to pressure.
- Osborne Reynolds: Known for the Reynolds number, which helps predict flow patterns in fluids.

What is pints per hour?
What is Pints per hour?
Pints per hour (pint/h) is a unit of volumetric flow rate, commonly used to express how much volume of a liquid is moving per unit of time. It is primarily used in the United States and some other countries that still use the imperial system of measurement. Let's break down what that means in simpler terms.
Understanding Pints and Hours
- Pint: A pint is a unit of volume in the imperial and US customary systems. There are different types of pints such as US liquid pint, US dry pint and Imperial pint.
- Hour: An hour is a unit of time.
Combining these, "pints per hour" tells you how many pints of a substance are flowing or being transferred in one hour.
Defining Pints per Hour
Pints per hour (pint/h) is a unit of volumetric flow rate. Volumetric flow rate also know as volume flow rate measure the amount of volume passes through a cross-sectional area per unit of time.
The formula for calculating flow rate is:
Where:
- = Volumetric flow rate
- = Volume (in pints)
- = Time (in hours)
Real-World Applications and Examples
- Beer Dispensing: You might see a beer tap described as dispensing at a rate of, say, 2 pints per hour for a slow, controlled pour or 10 pints per hour for fast dispensing at a busy event.
- IV Fluid Administration: In medical settings, IV fluids might be administered at rates measured in pints per hour, especially when dealing with larger volumes for resuscitation.
- Small Pumps: Small pumps used in aquariums or hydroponics systems might have flow rates specified in pints per hour to indicate how quickly they circulate water or nutrient solutions.
- Condensate Pumps: Condensate pumps that remove water produced by air conditioners or dehumidifiers might have flow rates specified in pints per hour.
- Sprinkler Systems: Very small sprinkler systems or drip irrigation systems could have application rates specified in pints per hour.
Considerations
- Viscosity: The flow rate can be affected by the viscosity of the liquid. More viscous liquids (like honey) will flow slower than less viscous ones (like water).
- Imperial vs. US Pints: Note that there are different pint sizes (Imperial and US), so it's essential to clarify which unit is being used. 1 US liquid pint is equal to 0.832674 Imperial pints.
- Other Flow Rate Units: Other common units for flow rate include gallons per minute (GPM), liters per second (L/s), and cubic meters per hour ().
Interesting Facts
While there isn't a specific law or historical figure directly associated with "pints per hour," the concept of flow rate is fundamental in fluid dynamics. Scientists and engineers like Daniel Bernoulli have contributed significantly to our understanding of fluid behavior, which is closely related to flow rate measurements.
