Question:

Why is hydraulic machinery so effective???

Answer:

Technically, working water will generate lots greater potential than a wave will. Hydroelectricity - An ocean wave might generate potential besides, even even though it require greater potential to supply the waves than the waves produce. additionally, with the intention to harness the finished potential of a wave you may could construct a gadget that captures the potential on a snapping factor. In sum, ocean waves are very lots too unpredictable to be sure that it for use as an outstanding source of potential.
very efficent transfer of power
becuase its powerful. but on the downside it may need to be replaced alot.
There is a huge mechnical advantage. The pressure in a fluid is the same everywhere in that fluid. Take your car brakes, for example. You can press a small plunger and increase the pressure on it to a very high pressure, let's say 100 psi. It is easy because you are compressing a very small area, lets say 1/2 square inch. That would take 50 pounds of pressure. But, one brake pad is equal to lets say 8 square inches. The total pressure exerted on the brake disk is 800 psi. Then you have 8 brake disks, each exerting 800 psi.
The simple reason is that Hydraulics utilizes fluid as opposed to Pneumatics (air) although both are referred to as fluid power , the liquid normally oil used in hydraulics is simply uncompressible. SO THE FLUID is essentially stronger than STEEL when a pump pushes the oil to a device like a cylinder, imagine the fluid being a solid BAR of STEEL say 6 inches in diameter, it is literally like pushing a bar of steel. Heavy equipment say could normally operate at say 2500 PSI out of the pump, since the pump pressure is essetially regulated, it is simply a matter of selecting the desired force and sizing say the cylinder (for instance) appropriatey. Since: Force = Pressure (pump pressure) times Area (of the cylinder) The forces are absolutely staggering with a quarter of a million pounds force off a 10 cylinder at 2500 psi pump output. the chart below may not have been converted properly, but if you work the equations, you will see that the incompressibility of the fluid is the secret to limitless amounts of power. Usually safety is the only limiting concern with hydraulics as it is easy to die working close to anything with such reserve and speed. Cylinder bore Force at 2500 psi 2 7,850 lbs 3 17,663 lbs 4 31,400 lbs 5 49,063 lbs 670,650 lbs 7 96,163 lbs 8 125,600 lbs 9 158,963 lbs 10 258,750lbs Pneumatics are faster usually, BUT NEVER as powerful due to the compressible nature of air.
