Carnot Heat Engine and Well-Insulated Piston Cylinder Systems
Q1) The working fluid contained in a well-insulated piston cylinder is expanded in a quasi-equilibrium process from 1000oF and 350 [psia] until the temperature is 150oF. Calculate the final pressure and volume and the work done by the system if
a. the working fluid is oxygen and specific heat is constant, and
b. the working fluid is steam
Q2) The heat addition process of a Carnot heat engine utilizing a piston-cylinder mechanism is executed by vaporizing saturated liquid R134a at 100 [kPa] to saturated vapor.
a. What must be true about the pressure during this process? Why?
b. Calculate the heat added during the process
i. Using the first law.
ii. Using the second law
