What is pints per second?
Pints per second (pint/s) measures the volume of fluid that passes a point in a given amount of time. It's a unit of volumetric flow rate, commonly used for liquids.
Understanding Pints per Second
Pints per second is a rate, indicating how many pints of a substance flow past a specific point every second. It is typically a more practical unit for measuring smaller flow rates, while larger flow rates might be expressed in gallons per minute or liters per second.
Formation of the Unit
The unit is derived from two base units:
- Pint (pint): A unit of volume. In the US system, there are both liquid and dry pints. Here, we refer to liquid pints.
- Second (s): A unit of time.
Combining these, we get pints per second (pint/s), representing volume per unit time.
Formula and Calculation
Flow rate () is generally calculated as:
Where:
- is the flow rate (in pints per second)
- is the volume (in pints)
- is the time (in seconds)
Real-World Examples & Conversions
While "pints per second" might not be the most common unit encountered daily, understanding the concept of volume flow rate is crucial. Here are a few related examples and conversions to provide perspective:
- Dosing Pumps: Small dosing pumps used in chemical processing or water treatment might operate at flow rates measurable in pints per second.
- Small Streams/Waterfalls: The flow rate of a small stream or the outflow of a small waterfall could be estimated in pints per second.
Conversions to other common units:
- 1 pint/s = 0.125 gallons/s
- 1 pint/s = 7.48 gallons/minute
- 1 pint/s = 0.473 liters/s
- 1 pint/s = 473.176 milliliters/s
Related Concepts and Applications
While there isn't a specific "law" tied directly to pints per second, it's essential to understand how flow rate relates to other physical principles:
-
Fluid Dynamics: Pints per second is a practical unit within fluid dynamics, helping to describe the motion of liquids.

Continuity Equation: The principle of mass conservation in fluid dynamics leads to the continuity equation, which states that for an incompressible fluid in a closed system, the mass flow rate is constant. For a fluid with constant density , the volumetric flow rate is constant. Mathematically, this can be expressed as:
Where is the cross-sectional area of the flow and is the average velocity. This equation means that if you decrease the cross-sectional area, the velocity of the flow must increase to maintain a constant flow rate in or .
-
Hagen-Poiseuille Equation: This equation describes the pressure drop of an incompressible and Newtonian fluid in laminar flow through a long cylindrical pipe. Flow rate is directly proportional to the pressure difference and inversely proportional to the fluid's viscosity and the length of the pipe.
Where:
- is the volumetric flow rate (e.g., in ).
- is the radius of the pipe.
- is the pressure difference between the ends of the pipe.
- is the dynamic viscosity of the fluid.
- is the length of the pipe.
