How much heat has to be removed from 3kg of boiling water (with mass fractions: 30% of liquid h2o and 70% of gaseous h2o) at constant pressure P=25 bar to make it a "compressed liquid" at temperature 140C. Assume that the specific heat of the substance at P=25 bar is temperature independent and equal to c_p=4.20 kJ/kg*K. Sketch the P-v and T-s diagrams of the cycle.
