Steam (water) at 105 Pa and 150 oC enters a water-cooled compressor at a rate of 0.008 kg/s. The exit state of the fluid is 10 MPa and 650 oC. The cooling water enters at 140 oC and leaves at 260 oC. The mass flow rate of the cooling water is 0.0035 kg/s. The cooling water remains liquid at all times. Determine the rate of change in entropy of the universe associated with this system. GIve your answer in kJ/Ks
For any spontaneous process, ∆Suniverse should be positive.
