One-half kg of Refrigerant 134a is contained in a piston-cylinder assembly, initially a saturated vapor at 200 kPa. The refrigerant undergoes a process for which the pressure-specific volume relation is p v^1.3 = constant, to reach a final state of superheated vapor at 400 kPa. Kinetic and potential energy effects can be neglected.
a. Solve for the specific volume at the end of the process.
b. Give the final temperature, and final specific internal energy (linear interpolation may be needed)
c. Evaluate the work involved in the process, in kJ. Did the system do work?
d. Determine the heat involved, in kJ.
