O You are running an industrial research study together with your project team to improve energy efficiency in a combustion process. The purpose of the research is to identify the optimum air-fuel ratio for the combustion process in a boiler under varying conditions of air supply and quality of fuel. The study would involve design of experiments, data collection and analysis, simulation of the different variables and validation of the optimum parameters. There is a lot of pressure to improve the energy efficiency as there is a forecast of fuel price rise in the forthcoming month. Based on the CRPE code of ethics, explain two critical precautions which the engineers have to consider before implementation of the data collection process for the industrial experiment. to be taken during the Describe briefly five ethical measures experimentaldata collection in order to ensure validity of results. Explain two precautions to be taken during the report writing on the research study carried out…

ECO 5. AUTOMOTIVE. The power an engine produces is called horsepower. In mathematical terms, one horsepower is the power needed to move 550 pounds one foot in one second, or the power needed to move 33,000 pounds one foot in one minute. Power, in physics, is defined simply as the rate of doing work. The formula below gives the horsepower at 5,252 radians per second. https://philkotse.com/toyota-corona-ior-sale-in-baguio/1991-for-sale-in-aid7017151 625T 1313 where H is the horsepower and T is the torque a.

Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown below. Your Analysis will be easier to do in EES but it is up to you. Your EES program must be well documented and documentation in your code should reference system sketches. (The cycle and individual components) These sketches are done on attached engineering or typing paper, unless you are able to draw them in EES. You must validate your results with hand calculations on engineering paper that invoke the 1 and 2 Law from the perspective of the entire cycle, not the individual components. Of course, a system sketch is required. nd 1. An ocean thermal gradient power plant using a simple non-ideal Rankine Cycle operates with a peak boiler temperature of 70 °F and a condenser temperature of 40 °F. The warm surface water of the ocean is supplying the thermal energy to the boiler. Assume a high source temperature of 80 °F. The cooler water deeper in the ocean is the sink for heat rejection at the condenser. Assume a…

Two sport utility vehicles (SUVs) are being considered by a recent engineering graduate. Using the following data evaluate which sport utility vehicle is better. Use six attributes in your a point, overall appearance, comfort, safety, reliability, and fuel mileage. Larger scores on overall appearance, comfort, safety, reliability, and fuel mileage are preferred to smaller ones. Click the icon to view the table with data you have gathered about the SUVs.

PLTW Engineering Activity 3.8 Precision and Accuracy of Measurement Introduction This concept of random and systematic errors is related to the precision and accuracy of measurements. Precision characterizes the system's probability of providing the same result every time a sample is measured (related to random error). Accuracy characterizes the system's ability to provide a mean close to the true value when a sample is measured many times (related to systematic error). We can determine the precision of a measurement instrument by making repeated measurements of the same sample and calculating the standard deviation of those measurements. However, we will not be able to correct any single measurement due to a low precision instrument. Simply stated, the effects of random uncertainties can be reduced by repeated measurement, but it is not possible to correct for random errors. We can determine the accuracy of a measurement instrument by comparing the experimental mean of a large number…
