heat, enthalpy of evaporation, is referred to as the energy required to change water into steam. Steam quality is referred to the percentage weight of the steam in a mixture of steam and water, that is, dry saturated steam contains no water. (Babcock & Wilcox Co., 2007). Saturated steam, which is steam at equilibrium with water, can only exit at specific pressure and corresponding temperature. Provided any change of temperature and pressure is made, the condition of steam will be impacted. For example
disasters involved failures of communication among ordinary professional people, working in largely bureaucratic companies. Two memos called the “Smoking Gun Memos,” authored by R. M. Boisjoly, of Morton Thiokol, and D. F. Hallman, of Babcook and Wilcox, will always be associated these two incidents. Unfortunately, neither of these memos were successful in preventing the accidents of the Challenger and the Three Mile Island near meltdown. R. M. Boisjoly: R. M. Boisjoly had over a quarter-century’s
Nature has its own way to show its power. Lightning is a bolt of highly charged particles that create huge amounts of electricity and heat that is hotter than the surface of the sun. It is an untamable force of nature. Man however has another means of power. Man’s lightning is fission; nuclear fission. A powerful yet tamable force that is harnessed for the clean use of our homes, appliances, and one day our vehicles. Man’s lightning is something that is feared by most, yet understood by few; a force
Globalization is changing the way of doing business in the world today. It is the new era of business opportunity. For many major companies, going global is a matter of survival, and it means radically changing the way they work. Economic globalization changes both spatial dimension of MNE’s (Multinational Enterprises) and creates a need for more flexible production of marketing systems and new forms of organization. Firms trying to position themselves as global players face problems such as the
On July 18, 1984 one of America’s most horrific and shocking killings took place in San Ysidro, California. A man originally from Ohio committed the fourth-deadliest shooting massacre by a single perpetrator in United States history, killing twenty-one and wounding nineteen others. The “McDonald’s Massacre”, as it came to be called, was a tragic event in a San Ysidro McDonalds. James Oliver Huberty was born on October 11, 1942, in the large city of Canton, Ohio. In year three of his life James had

Nuclear Crisis at Three Mile Island Abstract In March of 1979, just ten miles south of Harrisburg, Pennsylvania, the Nuclear Power Plant at Three Mile Island Unit 2 came close to nuclear melt down. Despite standards set by the Nuclear Regulatory Commission (NRC), the plant ran for several years prior to the accident under poor conditions. Communication certainly played a role in this near tragedy, as two engineers had foreseen the consequences, but their advice went unheeded. Although most
II. INDUSTRY PROFILE & COMPANY PROFILE 2.1 Industry Profile (Foundry Industry): Foundry industry is a branch of industry that produces the castings by filling molds with molten alloys. The volume of foundry production in the world is more than 80 millions. Casting is used to produce an average of 40%(by weight) of stock for machine parts, but in some areas of machine building, such casting appliance are tool manufacture, the percentage of castings is 80 percent. Appliance building in castings consumes
