1.
What is fluid power?
The technology of
generating, controlling and transmitting power using pressurized fluids is
termed as fluid power.
2.
State the basic methods of transmitting power.
1. Electrical - Power transmission over large distance.
2. Mechanical - Power
transmission to short distance and
3. Fluid power - Power
transmission for intermediate distance.
3.
State the type of fluid systems.
Fluid power systems - used to perform work.
Fluid transport systems -used for transporting fluids from
one place to another.
4.
State the law of conservation of energy.
Energy can neither be
created nor be destroyed but can be changed from one form to another.
5.
State the Pascal’s law.
Pressure applied on a
confined fluid at rest is transmitted undiminished in all directions and acts with equal force on
equal areas, and at right angles to them.
7.
Name some of hydraulic fluids.
Water, petroleum oils,
water glycols, water oil emulsion, phosphate esters and silicones are some of the hydraulic fluids used in fluid
power.
8.
Name few properties which a hydraulic fluid should posses?
Viscosity, Demulsibility,
Viscosity Index, Lubricity, Rust Prevention, Pour point, Flash Point and fire point and Oxidation
stability.
