GAS DYNAMICS AND JET PROPULSION 1. What is the basic difference between compressible and incompressible fluid flow? Compressible 1. Fluid velocities are appreciable compared with the velocity of sound 2. Density is not constant 3. Compressibility factor is greater than one. 2. Write the steady flow energy equation for an adiabatic flow of air. In an adiabatic flow q = 0. Therefore energy equation becomes. 2 c12 c2 h1 + + gZ1 = h2 + + gZ 2 + Ws 2 2 Incompressible 1. Fluid velocities are small

experience of the soldiers was beyond anything that had ever been faced before. A soldier who was attacked by poison gas says that “It seemed as if [his] lungs were gradually shutting up and [his] heart pounded away in [his] ears like the beat of a drum. On looking at the chap next to [him‚ he] felt sick‚ for green stuff was oozing from the side of his mouth.” (Pressey‚ “Poisonous Gas”). After getting attacked‚ this soldier isn’t only poisoned physically‚ but is poisoned mentally as he looks at the

After the Bhopal gas disaster in 1984‚ the Indian legislation governing safety and environment underwent significant changes.Specifically‚the factories Act was amended to assign the responsibility of the “occupier”‚who is legally responsible for the safety of the workplace and workers‚to the highest level of management in an organization. For a company this meant that one of the directors on the board had to be designated as “occupier”.The Environmental legislation also underwent changes ‚with the

Good afternoon‚ ladies and gentlemen. Firstly‚ let’s ask ourselves a few questions. How is my life now? Am I used to the air pollution or the unhealthy food? Only if you feel a little unsatisfied with your life quality‚ you may benefit from my today’s topic: LOHAS. It is very popular in the west. Now‚ one of four Americans has joined it and one third of Europeans have done so. You may still feel confused but don’t worry. Today‚ I will tell you what LOHAS is and its main characters in human’s basic

Introduction A gas is the state of matter that is characterized by having neither a fixed shape nor a fixed volume. Gases exert pressure‚ are compressible‚ have low densities and diffuse rapidly when mixed with other gases. On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem

• Natural gas is an odorless‚ colorless‚ flammable gas. It is non-toxic and lighter than air. • The gas chiefly consists of methane (CH4)‚ but also contains other hydrocarbons such as ethane‚ butane‚ propane and naphtha. Oil and gas deposits in the North Sea were formed millions of years ago through the decomposition and transformation of organic matter (plant and animal remains). In its primary form‚ natural gas can be used for residential heating and cooking‚ for industrial purposes

Arizona Gas Pipeline On July 30‚ 2003 an Arizona gas pipeline owned and operated by the Houston‚ Texas based company‚ Kinder Morgan Energy Partners‚ burst in Tucson and was shut down. A small portion of the 11-mile pipeline‚ which is about five feet underground burst and at least 10‚000 gallons of gasoline spilled; the pipeline rupture spewed gasoline 50 feet into the air. The Arizona gas pipeline cuts through Tucson’s South and West sides en route from El Paso‚ Texas to Phoenix‚ Arizona and
