HYDRAULIC THEORY Introduction A hydraulic system is defined as a‚ ‘machinery unit which uses fluid as a pressure medium’. It has a number of advantages over an electrical system of a similar working capacity. Advantages: (1) The power to weight ratio is at least 14 times better than an equivalent electrical system. (2) Self-resetting overload protection. (3) Self-lubricating. (4) Infinitely variable speeds. (5) No static electricity. (6) Linear motion.

Donna Fr July 15‚ 2013 Hydraulic Fracturing- Safe or Not When visiting family in Pennsylvania a couple of years back‚ I heard a new term called “fracking.” The towns were all a buzz about this new way to tap into Pennsylvania’s newest resource‚ natural gas. What I noticed was‚ a beautiful picturesque countryside being torn up. I saw trucks hauling water and equipment‚ traveling up and down small country roads. Farms that had been in family’s for generations being sold off or leased to gas companies

Hydraulic fracturing is when a hole or "well" is drilled deep into the ground‚ in an effort to extract valuable natural gas reserves which exist beneath the surface. The process of constructing a hydraulic fracturing well includes drilling into the Earth--first vertically and then horizontally‚ then lining the well with a two-terminal tube with one terminal that is filled with water while the other pipes the recovered natural gases up above ground (Withgott & Laposata‚ 2014). In order to exhume the

Hydraulic Fracturing Is a Bad Idea The man brought his lips among the cup‚ slowly taking a sip‚ then another. Sip after sip he drank from his glass then suddenly he dropped his glass and staggered backward. He gasped then collapsed on the floor. Paramedics soon arrived due to a neighbor’s distressed call. They rushed the man to the hospital. The doctors at the hospital realized that he passed out because of radioactive waste-water. As they conducted a further examination they determined he had

Hydraulic fracking is the method of extracting gas from sediments by injecting the area with a mixture of water‚ sand and other chemicals to release methane gas. Another source of fuel is the mining of coal. Unlike fracking‚ coal mining requires labor that is both physically demanding and hazardous. Mining for coal also requires a larger surface area and therefore could have a larger negative impact on the environment. The burning of coal contributes more CO2 emissions than the burning of natural

These companies’ practices of hydraulic fracturing have been very detrimental to the local populace. Hydraulic fracturing has been known to damage the environment through earthquakes and gas spills. In addition‚ it has been said that these companies have certain law exemptions that only they enjoy. These unsafe
