A 1-L can of R-134a is at room temperature, 20C, with a quality of 50%. A leak
Question:
A 1-L can of R-134a is at room temperature, 20◦C, with a quality of 50%. A leak in the top valve allows vapor to escape and heat transfer from the room takes place, so we reach a final state of 5◦C with a quality of 100%. Find the mass that escaped, the heat transfer, and the entropy generation, not including that made in the valve.
