Hydraulic Principles Flashcards
1
Q
Turbulent flow
A
Oil flows turbulently and creates a higher resistance
- sharp corners
- abrupt diameter changes
2
Q
Back pressure
A
Pressure created by resistance to flow on the return side of a system or component
3
Q
Energy
A
The ability to preform work
4
Q
What are the two states of energy
A
Kinetic
Potential
5
Q
What is force
A
The push or pull force that is capable of producing or changing the motion of a body
6
Q
How do kinetic and potential energy relate to hydraulic fluids
A
Potential - pressure
Kinetic - flow
7
Q
Metric output power
A
=flow rate (L/min) x pressure (MPa) x 0.0167
8
Q
Laminar flow
A
When the oil flows through system in straight parallel flows
- gradual corners
- smooth size changes
