Air in piston-cylinder assembly undergoes
athermodynamic cycle consisting of three internally
reversibleprocesses in series:
process 1-2: constant volume heating from t1=288k, p1=0.1mpa
top2=0.42mpa
process 2 -3: constant pressure cooling
process 3-1: isothermal heating to the initalstate
employing the ideal gas model with cp=1 kj/kg*k, evaluate
thechange in specific entropy, in kj/kg*k, for each process. sketch
the cycle on p-v and t-s coordinates. for eachprocess, associate
work and heat transfer with areas on thesediagrams,
respectively.
