Thermodynamic processes with water vapour

U ovom su radu opisani i analizirani termodinamički procesi s vodenom parom. Na početku rada opisana su karakteristična stanja vodene pare kada se koristi kao radna tvar u kružnim procesima. U središnjem dijelu navedeni su, detaljno opisani i prikazani termodinamički procesi s vodenom parom. Za svaki od procesa izvršen je termodinamički proračun u kojemu je izračunata toplina koju je potrebno dovesti, toplina koja se odvodi i dobiveni rad. Izračunat je i toplinski stupanj djelovanja kojim je moguće definirati učinkovitost procesa. Prikazom i analizom dobivenih rezultata uspoređeni su svi procesi ovisno o dobivenom radu i toplinskom stupnju djelovanja.In this paper the thermodynamic processes with water vapour are described and analyzed. At the beginning of the work, characteristic water vapour state points are described when it is used as a working fluid in cycle processes. In the central part, thermodynamic processes with water vapour are listed, described in details and shown. For each of the processes, a thermodynamic calculations were performed in which the heat to be delivered, the heat that needs to be discard and the received work were calculated. Thermal efficiency that is used to define the process effectiveness was also calculated. All processes are compared and analyzed based on the obtained work and the thermal efficiency
