• Hydraulic System Pump Pressure Cavitation
    528 words
    CAVITATION Cause and Effect The word cavitation is a process that a Hydraulics Technician does not want to encounter. Cavitation can occur due to entrained air bubbles in the hydraulic fluid or vaporization of the hydraulic fluid. This occurs when the suction lift is excessive and the inlet-pressure falls below the vapor pressure (pressure which a liquid starts to boil and thus begins changing into vapor) of the liquid. As a result, air or vapor bubbles, which form in the low-pressure inlet regi...

  • Mixer And Nozzle Process Description

    Mixer The hot air that is forced out of the combustor and through the turbine continues to exit the engine at the rearward. Before exiting however, this air must be mixed with the cooler bypass air that did not go through the compressor and combustor. These two air streams are mixed in order to quiet the engine. To understand how air can create noise, first consider the way water splashes and makes noise when a wave crashes. In the same way, when two different air streams traveling at extremely...

    Death is probably the most feared word in the English language. Its undesired uncertainty threatens society's desire to believe that life never ends. Don DeLillo's novel White Noise tells the bizarre story of how Jack Gladney and his family illustrate the postmodern ideas of religion, death, and popular culture.

    Noise Pollution Noise pollution is not a necessary price to pay for living in an industrial society. Much can be done to reduce the severity of the problem. For example, vehicles and other machines can be built to produce less noise. Four-cycle engines can replace much noisier two-cycle engines in such products as lawnmowers, motorboats, and jet skis. Labels that indicate the noise levels of appliances and tools can help consumers avoid noisy products and choose quieter alternatives. Even after ...
