Problem 4 (45 pts) One lb of water contained in a piston-cylinder assembly undergoes a constant pressure process from state 1 (initial state) to state 2, then a constant volume process from state 2 to state 3 (final state). Initially, the water is at 200 lbf/in and has a specific internal energy of 1208.9 Btu/lb. In the final state, the water is at 300 F and has a specific volume of 2.0 ft/lb. Kinetic energy and potential energy changes are negligible. Using the appropriate table(s) in your textbook, complete the following sub-questions: a) (15 pts) Indicate the phase of each state (subcooled liquid, superheated vapor, or saturated mixture). If the state is a saturated mixture, what is the quality x? b) (10 pts) qualitatively sketch the process on the T-v diagram provided on the right. Label two different types of lines that you can identify on the diagram. c) (20 pts) Calculate the work and heat associated with each process in Btu. Partial credits will be given if showing the right approach to analyze the problem. You can either itemize knowns, finds and sketch or group them together in one graph. List models and assumptions if they apply. T(F) v(ft/lb)
