Steam Turbines: A look into how a steam turbine functionsStacy L. Rousseau EE ’03 At a time when energy is such an issue in our country‚ it may be surprising to realize that the major technology involved in producing electrical energy today was developed over a century ago by Charles G. Curtis: the steam turbine. The aim of a steam turbine is to produce the maximum amount of electrical energy in the minimum amount of space. Today‚ steam turbines produce more electrical energy than any other system

The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that

Centrifugal pumps uses OF CENTRIFUGAL PUMPS: The applications of centrifugal pumps are numerous; however‚ these pumps are most often used in buildings for the following purposes: To pump the general water supply. This includes both the overhead and pneumatic tank systems. In general water supply systems where the pump takes off directly from the city pressure main or where no suction lift is required‚ a centrifugal pump can be used. When a centrifugal pump is being used with a suction

Global tight gas market is expected to reach USD 59.40 billion by 2020‚ growing at a CAGR of 3.6% from 2014 to 2020. Depleting conventional natural gas reservoirs around the world has prompted the industry to develop unconventional reserves which is expected to remain a key factor driving the market for tight gas. In addition‚ government support in the form of financial incentives and tax holidays is also expected drive the market over the forecast period. Favorable regulatory scenario in China‚

2. General Electric uses a multifaceted approach to help make them one of the industries leaders in engine production. This approach includes resources both financially and managerially. Financially General Electric has invested $50 million in new engine technology‚ with an additional $1.2 billion to $1.4 billion being required to help them bring new engine designs to the forefront. General Electric has also received a $20 million grant from NASA in order for them to create the first tester UDF

Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

WWI Paper: Draft One In the poem “Dulce et Decorum Est” written by Wilfred Owen‚ the audience is introduced to the horrifying experience of a gas attack in World War I. Owen goes into excruciating detail on every effect of the gas‚ and describes almost everything about the physical state of the infected‚ dying man. Thousands of soldiers were exposed to gas in the war‚ and unfortunately‚ many of them died from the effects. The first attack that the Germans unleashed on the allies was devastating.
