Dynamic Viscosity
Dynamic viscosity is a measure of a fluid's resistance to flow under an applied force. Poise (P) is the unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is named after the French physicist Jean Louis Marie Poiseuille.
Definition of Poise
- 1 Poise is equal to the dynamic viscosity of a fluid in which a tangential force of 1 dyne per square centimeter causes a velocity gradient of 1 centimeter per second between two parallel layers of the fluid that are 1 centimeter apart.
Relationship with SI Units
- In the International System of Units (SI), dynamic viscosity is measured in Pascal-seconds (Pa·s), where 1 Poise is equivalent to 0.1 Pa·s.
Common Usage
- While Poise is commonly used in the scientific and engineering fields, the millipascal-second (mPa·s) is more frequently used in industrial applications.
Conversion
- To convert Poise to SI units, you can multiply the value in Poise by 0.1 to get the equivalent value in Pascal-seconds.
In conclusion, Poise is the unit of dynamic viscosity in the CGS system and is used to quantify a fluid's resistance to flow. It plays a crucial role in various engineering and scientific applications where the flow behavior of fluids needs to be understood and controlled.
