A realtor for a residential real estate company in a large city has the business objective to develop a more accurate estimate of the monthly rental cost for apartments. The agent would like to use size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 25 apartments in a particular residential neighborhood and collects the following data (see Rent). b. Run a linear regression using size (in square feet)...

QUESTION 6 (5+5+5+5 = 20 marks) Microalloyed steels are an important class of steels used extensively by the automotive industry. The two most important contributions to the yield strength of these alloys are the strengthening by precipitates in the form of alloy carbides and the strengthening by ferrite grain size refinement. Consider a typical Nb microalloyed alloy composition: Fe-0.1C-1Mn-0.1Nb (wt. %). These alloys are hot rolled in the austenitic condition and then air cooled from elevated temperature. Figure 1 below...

4. A piston/cylinder contains pure oxygen at ambient conditions 20°C, 100 kPa. The piston is moved to a volume that is seven times smaller than the initial volume in a polytropic process with exponent n = 1.25. Find the final pressure and temperature, the specific work, and the specific heat transfer. Use table A.8 to find the internal energy at each state. Plot the process in a P – v diagram. 300 TABLE A.8 Ideal Gas Properties of Various Substances,...

5. The Martian atmosphere consists mainly of carbon dioxide with an average surface pressure of 700. Pa and an average temperature of -57 °C. A piston-based compressor is being designed to take ambient Martian gas and increase the pressure to 2.2 bar before it is processed for rocket fuel. CO2 is not CPG at these conditions -- you can assume it to ONLY be a TPG gas. a. Assuming the Mars atmosphere is pure CO2 and the compression process is...
