Question
H.W: Construct a process path for each of the following processes consisting of
sequential steps.
1. Nitrogen at 20 C and 200 mm Hg is heated and compressed to 140 C and 40 atm.
(One of an infinite number of possible solutions: Heat at 200 mm Hg from 20 C to 140
C, then compress isothermally from 200 mm Hg to 40 atm.)
2. Cyclohexane vapor at 180 C and 5 atm is cooled and condensed to liquid cyclohexane
at 25 C and 5 atm. The enthalpy change for the condensation of cyclohexane at 80.7 C
and 1 atm is known.
