In a cycle, initially there is water at $20$ psi and $900$f$,$ which through an adiabatic process reaches a condition of $20$ psia in which the liquid and steam are mixed with a quality of $84\mathrm{.}33\%$ steam, then a device makes all the steam becomes a liquid but saturated at the same pressure through an isochoric process, reaching the initial pressure and then reaching the point where everything started following an isobaric process.
