This slide just tells what is fluid power, its importance, properties and principles.

3. Components of Fluid Power

7. Pressure = Force per unit Flow = Volume per unit
 Pneumatics uses compressible gas as the fluid and Hydraulics uses
compressible.
 Pressure is measured with a mechanical dial type pressure gage.
b) Power and Efficiency
Power = P * Q
 The power available at any point in a fluid power system is the
pressure times the flow at that point.
 Cylinders, motors & pumps have input & output powers, which can
be calculate the efficiency of the components.

12. HYDRAULIC FLUID
FLUID COMPRESSIBILITY
 When a gas expands or contracts temperature needs to be considered.
The way the temperature behaves due to the compression or expansion of
a gas will effect the relationship between pressure & density.
