Project 2: In company that designs road cars and heavy trucks, it important to make the proper selection of the engines. Your part as a system energy engineer is to make a proper selection between an engine operates on Otto cycle/gasoline engine or Diesel cycle/diesel engine. Your head of department asked you to provide a detailed technical report that shows your selection for engine to be used with heavy truck vehicle. This is best achieved by performing the following tasks: Section.1: 1. Which engine does operate at lower ??? and has higher air-fuel mass ratio? 2. Which engine does burn fuel more completely? 3. Which engine has lower fuel cost? 4. Explain what compression ratio for Otto and Diesel cycles means 5. Explain what cut-off ratio for Diesel cycles means 6. Explain the limitations of SI engines in terms of their ability to operate at much higher compression ratios. What is this limitation called? 7. Provide general plot(s) for thermal efficiency, ? vs compression ratio, r…

Case Study – The New Engineer   Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator.  This is Jeff's first position after completing his engineering degree.  He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.   Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace.  They have never had an individual dedicated to this task full-time.  They will implement his recommendations if he can justify them.   As Jeff begins to get familiar with the operations, he spends considerable time on the production floor.  He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum.  They also use this liquid to clean residue from their skin.  They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.   In talking with the workers, Jeff learns of some of…

Directions: Answer the questions after each situation. 1. David Aquino, engineering director, started out the day uptight. His young child had the flu the night before, and he had been up all night to help. Upon arrival at his office, David had to make urgent phone calls to approve a two-week overtime work plan due to a plant fire the night before and to plan for a product committee meeting the next day to counter environmental concerns about a wastewater treatment plant. Then he spent 30 minutes reviewing the qualifications of new candidates and decided on one. He asked for salary information and wanted to examine the offer before it was sent. He asked for further justification for the budget requested by industrial engineering for a minicomputer. Without reading it, he approved the research proposal from material engineering. He rejected an invitation to speak at a regional meeting of the Philippine Society of Mechanical Engineers by giving an untrue reason. David made a note for the…

I'm a teacher needing this to be detailed

Introduction a. Write an introduction in 100 words about temperature and instruments used to measure temperature What are the different units of temperature? How can you convert between different units?

hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100pi  -1 h(10)=e66.84(10)/100pi  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

Task I:In order to generate electricity on a grand scale and provide it to all homes and businesses on a grid, the governments started developing power stations. Steam power plants work by removing thermal energy from a fuel source to transform water into steam. The steam that is created is used to turn a turbine. There are a variety of fuel sources that rely on steam to turn turbines to produce electricity. As a material engineer, your role is to select the best materials for the various parts ( Boiler, Turbine, and generator ) in the steam power station as in Figure 1. Your manager assigned you a project to do the following tasks   A .  Based on the electrical material properties, what will you choose to manufacture the rotor windings coils in the generator (Titanium, Copper, or PVC)? Give reasons for your choice. B. To insulate the outer cover of the generator, what will you use (Aluminium, Steel or PE)? Give reasons for your choice. C. If the blades of the turbine must have the…
