Unit Explanations
Pascal SecondPa·s
Source UnitThe pascal second (Pa·s) is the SI unit for dynamic viscosity, representing the internal friction of fluids. It quantifies the resistance of a fluid to flow when an external force is applied. A fluid with a dynamic viscosity of one pascal second will flow under a shear stress of one pascal at a rate of one meter per second. It is a derived unit, meaning it is defined in terms of the base SI units: kilograms (kg), meters (m), and seconds (s). The pascal second is critical in fluid dynamics, engineering, and various scientific disciplines where fluid behavior is studied.
Current Use
Today, the pascal second is widely used in various industries including chemical engineering, food processing, and materials science to characterize the flow properties of fluids. It is essential in applications involving lubrication, mixing, and fluid transport where understanding viscosity is crucial for efficiency and safety.
Fun Fact
The pascal second is named after Blaise Pascal, who also has the unit of pressure named after him.
Gram Centimeter Secondg·cm·s
Target UnitThe gram centimeter second (g·cm·s) is a non-SI unit of dynamic viscosity, which measures a fluid's resistance to flow. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a shear rate of one reciprocal second is applied. This unit is particularly useful in various scientific and engineering contexts, allowing for consistent measurements of fluid behavior under shear. The gram centimeter second unit is derived from the base units of mass (grams), length (centimeters), and time (seconds), making it an intuitive choice for fluid mechanics.
Current Use
Today, the gram centimeter second unit remains widely employed in laboratories and industrial applications to quantify fluid viscosity. It is particularly prevalent in the fields of chemistry, engineering, and material science, where understanding fluid behavior is critical. Various industries, including food processing, petrochemicals, and pharmaceuticals, utilize this unit to ensure product consistency and quality.
Fun Fact
The viscosity of a fluid can change with temperature; for example, heating oil reduces its viscosity.
