Floods could be very catastrophic as they are known to destroy property and cause deaths. When such catastrophic things happen, people from all over the world extend their generosity to the victims. Some people may take advantage of the situation to loot or take part in price gouging. The writer uses facts, emotional appeal and logical fallacies to support his argument. He uses vivid examples to sway his readers to the winning side of his argument. When volunteers stumble across information…

5.3 Optimum parameters obtained by Desirability analysis Figure 5.17, shows the optimality graph obtained by MINITAB 17 software for Brake specific fuel consumption, Brake thermal efficiency and Unburnt hydrocarbons of COME blends. The most favoured optimal condition obtained for Brake specific fuel consumption, Brake thermal efficiency and Unburnt hydrocarbons are shown. Optimization is carried out by using Derringer’s Desirability approach of RSM. Equations to calculate desirability are shown…

The Hepburn Act: Rough Draft In the early 1900s, there were approximately 250,000 miles of railroad track. These tracks were often regulated by corporations that had no concern for the citizens that were directly affected by the railroad. Imagine taking a train to go visit your family in the next state over; this sounds completely harmless in the modern time, but in the past, the passengers had to worry about their safety and the outrageously unfair travel rates. What our country needed during…

When studing liquid fuel combustion in gas turbine combustor, complicated principals including reactive flow, spraying, turbulent flow, multiphase flow, convective and radiative heat transfer and their interactions should be considered. In recent 40 years combustion chambers have continuously improved structurally. Present combustion chambers are generally devided to three main groups: Can type, Can Annular type, and Annular type chambers. Combustion chambers consist of components such as…

Minerals and their derived products are the foundation of many important industries. Mines and quarries can be found in almost every country all around the world. Mining industry products provide most of the needed energy, from electricity in homes and industries, to fuel in cars, machinery and tools Resources obtained from mines are also used as inputs for raw materials, consumer goods as well as for almost all services and processes provided by other industries, such as: manufacturing…

From the experimental study it is found that the heat transfer rate in notched fins is more than the un-notched fins. The average heat transfer coefficient increases with the heater input. It is clear that for the given heater input, average heat transfer coefficient of notched array is 30 to 40% higher than corresponding un-notched array. The average heat transfer coefficient for notched fin is better than un-notched fins. Also the copper gives more heat transfer rate than aluminum plate…

1. What are Seismic Imaging Technology and Chevron use of the technology? Seismic Imaging is a tool/technique to find the availability of crude oils and natural gas underground. It is also known as reflection Seismology as it is a process of inspection geophysics to evaluate the properties of Earth’s subsurface by using the principles of seismology from the reflected seismic waves. Sound waves are recorded by Seismologists using an ultrasensitive device called geophone as they echo under the…

Causes of the accident The direct and indirect causes connected to the sequence of events in the Bourbon Dolphin accident are listed below: Direct causes • External forces from weather and current; • Unfavourable heading of the vessel in relation to external forces; • Machinery black out and the consequent reduction of manoeuvrability; • Lowering the towing pin, which led to larger angle of attack; • Loading condition and vessel stability characteristics. Indirect causes • Weakness in…

Diesel engine The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engines have the highest thermal efficiency in any internal…

Machu Picchu, the Hidden Place The city of Machu Picchu, which comes from the Quechua language, has been abandoned by the Incas of Cusco for over three-hundred years. It also stands in the Andes Mountains and lingers over the Urubamba River. It’s elevated 10,000 feet and has walls that not even a credit card can not slide through, puzzling archaeologists for many years (Schreiber 1). Machu Picchu, located in Peru, is a place filled with amazing artifacts and ruins. The buildings’ architecture…
