Apiston–cylinder device contains steam that undergoes

a reversible thermodynamic cycle. initially the steam is

at 400 kpa and 350°c 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 the net

work and heat transfer for the cycle after you calculate the

work and heat interaction for each process.
