7. Hydraulic cranes. 8. Hydraulic shaper.
9. Agriculture equipment. 10. Railways, Aerospace.
1. Pneumatic tools: Drilling m/c, nut runner, screw driver etc.
2. Packing m/c. 3. Material handling: Clamps, conveyor, robotic arm.
4. Mining 5. Automobile: Air brake, Air suspension etc.
6. Machine tools: Pneumatic press, clamps, vices etc.

5. 1. To avoid mechanical linkages (belt, pulley, chains, gears,
sprockets etc.
2. Breakdown reduces and production increases.
3. Design and construction is easy, simple & compact as pipe is
flexible.
4. Automatic and safety are possible to avoid accident and
increase production.
5. Modification is easily implemented.
6. Vibration, noise, wear and tear are reduces.
7. Maintenance, servicing and lubrication is simple.
8. Very precise speed control achieved.
9. If overloaded, the system stalls. System will start working
again once the load is reduced.
10. It create huge amount of force.B.P.P. Kalamb-Walchandnagar Prof. Kokare

6. 1. Mass Density: mass of liquid per unit volume in kg/m3
(water-1000 kg/m3)
2. Weight Density: weight of liquid per unit volume in N/m3.
(water-9810 N/m3).
3. Specific (relative)Gravity: ratio of density of liquid to density
of water. (s)
4. Compressibility: It is ability of fluid to get compressed.
5. Viscosity: resistance offered by liquid to flow.
6. Dynamic viscosity: shear stress per unit rate of shear strain.
7. Kinematic viscisity:ratio of dynamic viscosity to mass density
8. Neutralization number: The number of miligrams of
potassium hydroxide (KOH) required to neutralize one gram
of oil.
B.P.P. Kalamb-Walchandnagar Prof. Kokare
A.Y.

7. 9. Flash point: The temp. at which the oil gives-off momentary
flash. (It should be high as possible)
10. Fire Resistance: It is property which resist burning.
11.Specific (relative)Gravity: ratio of density of liquid to density
of water. (s)
12. Oxidation Stability: Oxidation is a chemical reaction in which
oxygen combine with oil and it affect property.
13. Lubricity: It is ability of an oil to reduce friction & wear
between moving element.
B.P.P. Kalamb-Walchandnagar Prof. Kokare
A.Y.

8. 1. Oil should be incompressible.
2. Oil should have sufficient lubricating properties.
3. Oil should have sufficient viscosity index.
4. Oil should be chemical stable.
5. The Pour point of oil should low.(will not solidify at least 1500c
6. The Flash point of oil should high.
7. The oil should not acidic. (will not corrode)
8. The oil should have good oxidation resistance.
9. The oil should be non-toxic.
10.The oil should have anti-foam.
11.The oil should have good demulsibility.(to separate out water
12.The oil should have anti wear and ant rust properties.
