Free Respоnse Prоblem (10 pоints) - write down your step-by-step solution Wаter in а verticаl, well-sealed, frictionless piston-cylinder device undergoes a two-stage process. The water is initially cooled from P1 = 300 kPa and T1 = 250°C (state 1) until its specific volume is one-third its initial value (state 2). At state 2, the piston has barely contacted the stops that restrict its downward movement (i.e., small black rectangles in the diagram below). The cooling then continues until the water reaches T3 = 90°C (state 3). a) Draw a physical schematic in your answer sheet. Clearly identify the system boundary and show all relevant energy interactions between the system and the surroundings for each process. b) Fill in the table of property values shown below (copy the table on your answer sheet). If the quality at a given state is not applicable, write “N/A” State Pressure (kPa) Temperature (°C) Specific Volume (m3/kg) Quality (%) 1 2 3 c) Sketch the complete process on T-v and P-v diagrams. Draw the isotherms and isobars associated with each state. Please also include symbolic labels for each property value on the corresponding axis (e.g., T1 for the temperature at state 1).
