A piston-cylinder assembly contains a mystery substance that undergoes a series of processes. Process 1-->2: Constant pressure process at 5bar from v1=.07m3/kg to v2=.12m3/kg Process 2->3: Constant volume process to saturated vapor Process 3->4: Constant temperature process to quality of 50% Process 4->5: Constant volume process to 5bar Sketch the processes on Pt, Pv, and Tv, plots. Lable the axes including property values; use closed dots to show the states, use solid lines to connect the states, add number and arrows to make clear the states numbers and process directions. Could this be considered a thermodynamic cycle? Why or why not?
A piston-cylinder assembly contains Refrigerant 22, initially a saturated vapor at 5 bar. The refrigerant undergoes a process for which the pressure-specific volume relationship is pv = constant to a final pressure of 20 bar. Kinetic and potential energy effects can be neglected. a. For your schematic, provide a rough sketch of your system, with arrows indicating direction of work and heat (i.e, in or out of the system) b. Determine the work and heat transfer for the process, each in (kJ/kg)

Water undergoes two processes in series: • 1 to 2: isentropic (internally reversible and adiabatic) compression from 0.1 MPa and the phase of water is “saturated vapor” to 0.5 MPa• 2 to 3: a reversible isothermal process to 1.5 MPaa) Draw the overall process on a T-s diagram. Clearly indicate all states and the values of the relevant intensive properties on your diagram. b) Is process 2 to 3 a compression, expansion, or isochoric process? How do you know? c) Determine the overall specific work (w13) and specific heat transfer (q13) for this complete process. (Hint: recall that Q int rev =∫ T ds21 for an internally reversible process between states 1 and 2.)
X Your answer is incorrect. A rigid tank whose volume is 4 m³, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 350 K. Assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kJ.
