GP111 Elementary Thermodynamics Gas , vapour Power and refrigeration cycles 1 Introduction • Both power generation and refrigeration are usually accomplished by systems that operate on a thermodynamic cycle: power cycles and refrigeration cycles. • Power producing devises: engines • Refrigeration producing devices: refrigerators, air-conditioners and heat pumps. 2 Basic considerations in the analysis of power cycles • Cycles encountered in actual devices are difficult to analyze because of the presence of complicating effects such as friction etc. • Consider a cycle that resembles the actual cycle closely but it made up totally of internally reversible process (ideal cycle) Wnet Thermal efficiency ,  th = Qin or wnet qin 3 Idealizations and simplifications • Cycle does not involve any friction: no pressure drop in the working fluid. • Expansion and compression process: quasi equilibrium. • Pipes connecting various components are well insulated. • Neglecting changers in KE and PE 4 Net work of the cycle 5 Carnot cycle • The Carnot cycle is the most efficient cycle that can be executed between heat a source and a heat sink.  th,Carnot TL = 1− TH 6 Air-standard assumption • Gas power cycles (working fluid gas): spark ignition engines, diesel engines, conventional gas turbines, etc. • All these engines energy is provided by burning a fuel within the system boundary. • Working fluid (air) mainly contains nitrogen and hardl ...

STA 3215 CBE Rasmussen Earthquake Depth and Magnitude Correlation Analysis PPT

ScenarioAccording to the U.S. Geological Survey (USGS), the probability of a magnitude 6.7 or greater earthquake in the Greater Bay Area is 63%, about 2 out of 3, in the next 30 years. In April 2008, scientists and engineers released a new earthquake forecast for the State of California called the Uniform California Earthquake Rupture Forecast (UCERF).As a junior analyst at the USGS, you are tasked to determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and depths from the earthquakes. Your deliverables will be a PowerPoint presentation you will create summarizing your findings and an excel document to show your work.Concepts Being StudiedCorrelation and regressionCreating scatterplotsConstructing and interpreting a Hypothesis Test for Correlation using r as the test statisticYou are given a spreadsheet Click for more optionsthat contains the following information:Magnitude measured on the Richter scaleDepth in kmUsing the spreadsheet, you will answer the problems below in a PowerPoint presentation.What to SubmitThe PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above.Slide 1: Title slideSlide 2: Introduce your scenario and data set including the variables provided.Slide 3: Construct a scatterplot of the two variables provided in the spreadsheet. Include a description of what you see in the scatterplot.Slide 4: Find the value of the linear correlation coefficient r and the critical value of r using α = 0.05. Include an explanation on how you found those values.Slide 5: Determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and the depths from the earthquakes. Explain.Slide 6: Find the regression equation. Let the predictor (x) variable be the magnitude. Identify the slope and the y-intercept within your regression equation.Slide 7: Is the equation a good model? Explain. What would be the best predicted depth of an earthquake with a magnitude of 2.0? Include the correct units.Slide 8: Conclude by recapping your ideas by summarizing the information presented in context of the scenario.Along with your PowerPoint presentation, you should include your Excel document which shows all calculations using the excel functions.
