What is hydraulic multiplication?
hydraulic multiplication is using incompressible fluids to transfer force from one are to another and in the process multiply the force being transfered. because pressure remains constant in a closed system, such as this, the pressure in the fluid is equal, it is constant, it does not change, therefore the bigger the area, the bigger the force.
What is the definition of green-field projects?
hehe punta ka d2 sasabihin ko ang sagot...!!bleeehhhh..:D peace
Is hydraulic fluid and hydraulic oil the same thing?
Hydraulic oil and hydraulic fluid are different.
Hydraulic fluid is used in small systems such as car brakes.
Hydraulic oil is used in large systems such as loaders.
What is the difference between HD-46 and HD-68 Hydraulic oil?
Basically, the only difference between HD-46 and HD-68 hydraulic oils is the weight of the product. HD-46 is a 15 weight oil, but HD-68 is a 20 weight oil.
What are the Pros and cons of hydraulic system?
Generally hydraulic systems are closed circuit, meaning that the liquid used (generally oil) is filtered and stored in a reservoir. pneumatic systems are often open, as air from the atmosphere is compressed in a tank before it is used, then released into the atmosphere afterward. the air tank is either charged before operation of the system, or continuously replenished by a compressor, (the compressor is run by a prime mover). the primary disadvantage of pneumatics, is that gas can be compressed, and decompressed, this is an advantage for storage, but makes control difficult. hydraulic systems do not have this problem, but the liquid in the system must be recirculated, thus requiring more maintenance, and also storage, as liquids do not compress. this is beneficial to control, because the liquid in a hydraulic actuator cannot be compressed, this provides rigidity when the liquid is not flowing, and precision when it is. another benefit of this rigidity is that good leverage is not needed in hydraulic systems many pieces of heavy machinery use third class levers with hydraulics because the mechanical advantage of a large hydraulic piston combats the poor leverage, a telescopic handler, wheel loader, and telescoping crane excellent examples of this. (include pictures of green forklift with log, grove crane and wheel loader on this slide)
Difference between hydraulic fluid and hydraulic oil?
There is no difference that I am aware of. These terms seem to be used interchangably.

d) hydraulic
e) electrical
How do you make hydraulic cement?
How to make hydraulic cement.Stir dry in a wheel barrel.
50 lb bag portland
80 lb bag masonry cement
50 lb bag play sand or silica sand
15 lb Plaster of Paris or Molding Plaster
Note: Be sure all the plaster is displaced evenly throughout the barrel.
Scoop out the amount you need and just add water.
Work quickly to mix water with hydraulic material
Stir immediately!
Fast-setting - sets in 3-5 minutes
Performance - instantly stops seepage
Pre-blended - just add water

Who explained the operation of a hydraulic lift system?
Bernoulli's principle.
The above answer is wrong.
Its Pascal's Principle :)
How does electro hydraulic governor functions?
governor has 3 modes of operation
1.SPEED CONTROL MODE-before sychronisation the governor runs in speed control mode.guide vanes open up and the turbine runs in the rated speed.when the governor gets connected to the grid that is when it gets synchronised then the speed control mode terminates.
2.OPENING MODE-load is increased in this mode and teh machine runs in the rated speed only.
3.POWER CONTROL MODE-it has two modes.joint controller and indivisual controller mode.in joint controller mode all the machine works all together and in the indivisual controller one setup point is given to the governor and the guide vanes vary accordingly
What are some advantages and disadvantages of hydraulic systems?
Advantages
High horsepower, low weight
Low speed torqueConstant force or torque
Safety in hazardous environments
Disadvantages:
can easily cause burns and irritations due to pressurized fluid.
How do you purifier hydraulic oil?
Hydraulic oil, also called hydraulic liquids, are the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic oil include excavators, brakes, power steering systems, transmissions, backhoes, garbage trucks, aircraft flight control system and industrial machinery.
Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic oil used has low compressibility. But actually, after some time operation, the hydraulic oil quality will be changed as it can be contaminated by impurities, gases and plenty of water, and become emulsified. So in this case, after certain time operation, the used hydraulic oil must be filtered reguarly, in order to keep its good function of lubricating.
TYA series vacuum hydraulic oil purification machine is just a reliable machine for recovering these used emulsified hydraulic oil, here is the introduction of this model:
Technology and advantages of TYA series:
1: Rapid speed for dewatering, degasify and removing impurities from waste high voscosity lube oil used for lubricating equipments, and after treatment, the treated oil can reach to cleanness NAS 6.
2: Strong capability of breaking emislfied thoroughly with special material filters.
3: Adopt advanced technology for combination of coalescing separation and vacuum dewatering, to get the high precise of water and gas content.
4: Newly developed auto double-infrared fluid level control system, replace of manual or floating ball valve control, to ensure operation safety of this model.
5: Automatic back-flushing system, can clean the filters by the machine itself, to timely maintain the filters and extend its service life.
6: Carbon fiber infrared heating system not only can heat the oil equably and rapidly, but also a environment-friendly way for oil heating.
7: Nice outlook of the machine, advanced design, reliable quality, reasonable price and considerate service.

Hydraulic energy is an energy transfer from the water to waterwheels and mills.
What are the three different types of actuator called?
- MOTOR are powered by electrical signs from the computer.
- HYDRAULIC ACTUATORS are powered by fluid pressure controlled by the computer.
- PNEUMATIC ACUATORS are like hydraulic ones but are powered by air pressure insted.(less powerfull than hydraulic)
An Example of hydraulic power sysrem?
The ram on a digger is one example. Also, hydraulic motors which drive some machinery like combine harvesters are another. The pump itself forms part of the system in both cases.
What is hydraulic height as it relates to a dam?
The pressure that water exerts on the walls of the dam is proportional to the depth of the water or you might say the height of the column of water from the base of the dam. The hydraulic height is the same as the depth of the water to the bottom of the dam.
What is an example of a hydraulic system?
Force that is applied at one point is transmitted to another point using an incompressible fluid. for example a lift cylander on a dump truck
Used where there's a need to produce a greater force using a smaller force.
E.g. Car brakes
Lifting cars in garages
How does hydraulic action work?
hydralic action works when the wave came and the sea water are toching together
Hydraulics is a topic of science and engineering dealing with the mechanical properties of liquids. Hydraulics is part of the more general discipline of fluid power. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. Hydraulic topics range through most science and engineering disciplines, and cover concepts such as pipe flow, dam design, fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior and erosion.
The word "hydraulics" originates from the Greek word ὑδραυλικός (hydraulikos) which in turn originates from ὕδραυλος meaning water organ which in turn comes from ὕδωρ (water) and αὐλός (pipe).
Describe the laminar sub-layer in hydraulic?
this is the region in the turbulent boundary layer zone,adjacent to the solid surface of the plate. in this zone, the velocity variation is influenced only by viscous effects.
