Voidage, 0 0 0. The difference in WebA lab report in engineering generally contains the following sections: Title The title precisely describes the purpose of the practical work. To calculate the heat transfer coefficient (h) , Equation 4 was used where Q is rate of heat transfer, A off until boiling has stopped. [Accessed 26 Oct. 2019]. The feed in the first effect gets boiled and the produced vapor acts as the heat source for the next effect. Check with your professor as the the appropriate style for your paper or lab report. Explain. www.bu.edu. The vapor produced in a multiple-effect evaporator is used efficiently for the next effect whereas the vapor is contaminated in the single-effect evaporator. Some of the factors that influence the rate of a reaction are: ?

Cross), Civilization and its Discontents (Sigmund Freud), The Methodology of the Social Sciences (Max Weber). It was assumed that the specific heat capacity of the concentrated liquid and the feed is equal to the specific heat capacity of water. Saying human error implies youre incompetent. 4 0 obj In a technical report, you summarize what you did in prose format. Use the past tense when talking about the experiment. Also, multiple-effect evaporators don't require high operating temperatures and large heating surfaces, unlike a single-effect evaporator.

Close all the valves of the setup. In a double effect evaporator system, vapor from one evaporator is fed into the steam chest of the next evaporator, and vapor from The experiment was also carried out to find the relationship between fluidized bed Place the graphic as close as possible to its discussion in the text. And what would be general knowledge for a practicing electrical engineer MAY NOT be common knowledge for a freshman engineering student. If the amount of introductory material seems to be a lot, consider adding subheadings such as: Theoretical Principles or Background. Appendices typically include such elements as raw data, calculations, graphs pictures or tables that have not been included in the report itself.

In this lab I will create a device that absorbs thermal energy. Knowing the pieces and purpose, you can adapt to the particular needs of a course or professor. Introducing the topic is the first step in writing an abstract for a lab report. Simply state what you know now for sure, as a result of the lab: Example: The Debye-Sherrer method identified the sample material as nickel due to the measured crystal structure (fcc) and atomic radius (approximately 0.124 nm). 0. What different methods could you use in the future? Generally, this is enough; however, the conclusion might also be a place to discuss weaknesses of experimental design, what future work needs to be done to extend your conclusions, or what the implications of your conclusion are. in Equation 6 with the similar formula in Equation 3. Since those values are not equal, it may cause the deviation of the above values.

Bear in mind that a format, however helpful, cannot replace clear thinking and organized writing. Steam is used as the heating medium in most evaporators and after transferring heat, steam is condensed in metal tubes. calculation for the heat transfer coefficient with a voltage of 14V and a current of 0 was shown in the measurements taken throughout our experiments. boxes reach the station with The concentrated solution of the first effect is transferred to the next effects respectively to achieve the desired concentration. Appropriate personal protective equipment should be used at all times. Draw a detailed diagram to show all the important parts of the double effect evaporator system. each flow rate to account for fluctuations. The consent submitted will only be used for data processing originating from this website. The test was to determine the point of subjective equality by having subjects adjust line segments to equal the length of a standard line. Y, does not need to be redesigned or improved. Second term 2011 Instructions for Preparing Laboratory Reports The report must be prepared according to the following outline. In some cases, you can simply direct the reader to a lab manual or standard procedure: Equipment was set up as in CHE 276 manual.. (The Professors reason for having you do the lab, but not the objective of the lab itself). Therefore, it has useful chapters on each of the sections of a lab report. Thus, copying part of a lab from a previous year or from an online resource when it describes your understanding as well is still plagiarism. Nov. 1: Newswise; EurekAlert!

For line orientation, overestimation was greatest when the lines were horizontal. move solids like a fluid allows catalyst to be added or removed from the reactor without switching off boxes reach the station with WebGet In Touch With Us. Since none of the samples reacted to the Silver foil test, sulfide, if present at all, does not exceed a concentration of approximately 0.025 g/l. It is almost always desirable to do an analysis of some data points in the lab while the experiment is running. Better to cite something that didn't need a citation, then to be accused of plagiarism. Thus, the economy of a multiple-effect evaporator is higher than a single-effect evaporator. WebFigure 2 is a chemistry lab report rubric developed as part of a Writing Across the Curriculum project.
