H2O flows through a constant pressure steady heat exchanger in an internally reversible process. The inlet condition is 100 kPa, and the inlet quality is 1.  The outlet quality is zero.  The mass flow rate is 2 kg/s. At what rate is entropy entering the system in kJ/(K*s) at the inlet As 1 kg of mass flows from the inlet to the exit, how much heat flows from the 1 kg? (kJ) As 1 kg of mass flows from the inlet to the exit, what is the entropy change in the kg of H2O?  Did the entropy increase or decrease? At what rate is entropy exiting the system with the H2O at the outlet kJ/(K*s)
