Textbook Question
Chapter 1, Problem 1.15P
A race engine shop has just completed two engines of the same design. How might you, the team engineer, determine which engine would perform better for an upcoming race (a) based on a test stand data (engine dynamometer) and (b) based on race track data? Describe some measurements that you feel might be useful, and explain how you might use that information. Discuss possible differences between the two tests and how these might influence the interpretation of the results.

Your team started by assessing the boiler and steam network. You gathered the following information:
The boiler operates at a pressure of 7 bar.
The AF ratio is adjusted manually.
The steam network is insulated, except at certain points where fittings and valves are present
No visible steam leaks.
The exhaust gas temperature is 330°C.
The O2 percentage in the exhaust was found to be 8.5%.
Maintenance is not regular.
The boiler consumed 23,000 GJ of natural gas in 2022 (price of natural gas is JD 7.5/GJ). Prepare a short note (to be incorporated in the audit report which your team leader will compile) to provide your assessment of the boiler and steam system. Your contribution should include the following:
1. Estimation of current boiler efficiency.
2. Measures that can be taken to improve the boiler efficiency.
We learned that engine design can alter / change engine performance, that by increasing the engine displacement, engine power can be increased. Experts commonly agree that there are three (3) ways to increase the displacement of an engine.
Question: 1)Explain the 3 ways of increasing the engine displacement?
2) Explain the commonly used alteration method used by car racers.
Truncation errors are increased as the round-off errors are decreased.Group of answer choices True False

Quality can also be defined as "conformance to specifications". In theory, if you create the right specifications and then manufacture a product that meets these specifications, you should achieve customer satisfaction. Consider the following four scenarios for a particular product: A) Conforms to specifications and is competitive in its adequacy. B) Conforms to specifications and is not competitive in its suitability. C) It does not conform to specifications and is competitive in its education. D) Does not conform to specifications and is not competitive in its education. Which of these are not, in theory, feasible, but in practice occur and cause a lot of conceptual confusion?
