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?

Which of the following is incorrect about the overall energy balance and mechanical energy balance in fluid flow phenomena?A. The former only accounts the first law of thermodynamics while the latter includes the second.B. The former only accounts the work brought by changes in the volume while the latter includes the Δ(PV) work.C. The enthalpy of the system for both balance is the sum of the changes in the internal energy and the reversible work at constant pressure.D. The former is not often used to evaluate a system with changing pressure unlike the latter.
