A stream of propane is throttled from 20 bar and 518 K to 0.42 bar. This process is irreversible due to frictional losses at the nozzle.
c. Why are frictional losses irreversible?
d. What is the final temperature of propane (after throttling)? The ideal gas constant?pressure heat capacity of propane is 92.7 J/mol/K. Clearly state any assumptions you need to make to solve this problem.
