Carbon monoxide gas (CO) contained within a piston– cylinder assembly undergoes three processes in series: Process 1–2: Expansion from p1 = 4.5 bar, V1 = 0.8 m3 to V2 = 1.4 m3, during which the pressure-volume relationship is pV = constant. Process 2–3: Constant-volume heating from state 2 to state 3, where p3 = 4.5 bar. Process 3–1: Constant-pressure compression to the initial state. Evaluate the overall work, in kJ and graph

One kilogram of water is contained in a piston-cylinder device at 100 degC. The piston rests on lower stops such that the volume occupied by the water is 0.835 m3. The cylinder is fitted with an upper set of stops. When the piston rests against the upper stops, the volume enclosed by the piston-cylinder device is 0.841 m3.

A piston–cylinder device contains steam that undergoes a reversible thermodynamic cycle. Initially the steam is at 400 kPa and 350oC with a volume of 0.3 m3. The steam is first expanded isothermally to 150 kPa, then compressed adiabatically to the initial pressure, and finally compressed at the constant pressure to the initial state. Determine (a) the net work and heat transfer for the cycle after you calculate the work and heat interaction for each process and (b) show the cyclic...
