Superheated water vapor at a pressure of 175 bar, a temperature of 450 C, and a flow rate of 12 kg/hr was brought to a saturated vapor state at 100 bar by mixing this stream with a stream of liquid water at 40 C and 150 bar. The flow rate for the liquid stream was found to be 7.35 kg/min. a) Draw a suitable figure of the process with process conditions and flow rates. [5 Points] b) Apply and formulate the 2nd law of thermodynamics for this process. Potential and kinetic energies can be neglected. [10 Points]. c) Calculate the entropy generated during this process? [5 (correct assumptions & logic) + 2 (correct formula) + 10 (correct calculation) + 3 (correct data reference) + 5 (correct answer and SI units) = 25 Points]. d) Does the entropy increase, decrease or remain the same? Explain. [10 Points] Note: Explain your answer where required
