... between pressures p1 = 1.6 bar and p2 = 6 bar. The refrigeration cycle consists of four processes as sketched in the figure below. The refrigerant is compressed ideally from a saturated vapor at station 1 to a superheated gas at station 2, cooled in a heat exchanger from superheated gas to a saturat ...

... another extensive property. Example: V → V /N . 2. Notation. Inconsistent notation has plagued thermodynamics perhaps since the beginning. The key in reading any text is to find out what the notation means before you read. There are basically four types of variables: (a) Extensive: e.g. V , U , N , ...
