Two kilograms of steam contained in a horizontal frictionless piston as well as cylinder initially at 250C and 4.81m3 are cooled isobarically until the volume decreases by 19.5%. Presume that heat is transferred at 190C.
a) Find out the work heat as well as entroppy generation for the process.
b) Repeat part a Presume that steam is an ideal gas with a Cp=43 J/mol*K.
