Tips & Best Practices
-
Ensure you input dynamic viscosity values under standard conditions for accurate conversion
-
Be cautious when converting measurements involving temperature variation or non-Newtonian fluids
-
Use the tool to maintain consistent units in reports when collaborating across different scientific disciplines
-
Refer to proper unit definitions to avoid confusion between related viscosity units
Limitations
-
Pascal second is the preferred SI unit in scientific contexts; poise is mainly used in CGS or legacy systems
-
Conversion assumes standard conditions and may not reflect changes at varying shear rates or temperatures
-
Complex viscosity behaviors such as those in non-Newtonian fluids require careful interpretation beyond this simple conversion
Frequently Asked Questions
-
What is pascal second [Pa*s] used for?
-
Pascal second is an SI-derived unit used to measure dynamic viscosity, commonly applied to specify lubricant viscosities, analyze fluid flow in engineering, and report rheological properties in labs.
-
Why convert from pascal second to poise?
-
Converting from pascal second to poise helps compare dynamic viscosity values between SI and CGS systems, which is essential for working with legacy data or specific industry standards.
-
Does this conversion consider temperature or non-Newtonian fluid effects?
-
No, this conversion assumes viscosity under standard conditions and does not account for temperature variations or complex fluid behaviors.
Key Terminology
-
Pascal second [Pa·s]
-
The SI derived unit of dynamic viscosity, indicating resistance to shear flow measured as pascals of shear stress per shear rate.
-
Poise [P]
-
A CGS unit of dynamic viscosity equal to 0.1 Pascal seconds, used to quantify fluid resistance to shear in absolute terms.
-
Dynamic viscosity
-
A measure of a fluid’s internal resistance to flow when subjected to shear stress.
