A cylinder fitted with a piston contains water at 16 bar and 400 °C. Water is cooled by following two paths in series (consecutively). Path 1-2: Water is cooled to the saturated vapor state while pressure remains constant. Path 2-3: Water is cooled to the pressure of 8 bar while volume remains constant. a) Sketch both paths on P-v and T-v diagrams. b) What is the temperature of the water at the end of the process? c) Determine the final state of water. If it is mixture, evaluate the quality (x). d) Calculate the work as kJ/kg for overall process, e) Calculate the heat transfer as kJ/kg for overall process.
