Fluid Power Systems Flashcards
1
Q
What is dynamic or absolute viscosity (Pa.s)
A
It is the shearing resistance of the fluid and is measured by placing the fluid between two plates one with respect to the other. Viscosity of a fluid is it’s resistance to flow
2
Q
What is bulk viscosity
A
Property that indicates the springiness of the fluid and is defined as the pressure needed to cause a given decrease in volume
3
Q
What is pascals law
A
In a confined fluid at rest, the pressure acts equally in all directions and acts perpendicular to the confining walls.
