Basic Principles

Question 1

Pascal’s Law

Answer 1

Pressure applied to a confined liquid is transmitted undiminished in all directions, and acts with equal force on all equal areas, and at right angles to those areas.

Question 2

Pros and Cons of hyrdraulics

Answer 2

High power to weight ratio

Poor transmission over long distances
Dangerous bc high pressure

Question 3

What creates Pressure?

Answer 3

Resistance to flow

Question 4

Series vs Parallel flow

Answer 4

Series: Pressure adds up

Parallel: Flow takes path of least resistance

Question 5

What are the components which create pressure?

Answer 5

Prime Mover
Pump
Actuator

Question 6

Cavitation

Answer 6

When the pressure in the fluid decreases below the vapour pressure, it vapourizes into gas bubbes which then collapse. The collapse can damage components.

Question 7

Aeration

Answer 7

Gas bubbles introduced into the system due to a leak. Similar issues as cavitations
