Water contained in a piston-cylidner assembly undergoes 2 processes in series from an initial state where the temperature is 150 degrees Celsius with quality x=50% Process 1-2: The water us heated at constant volume until it reaches the saturated vapor state Process 2-3: The water is then heated at constant pressure to 400 degrees Celsius a) Sketch both processes on T-v and P-v diagrams b) For the overall heating process determine the work in kJ/kg c) For the overall heating process determine the heat transfer in kJ/kg
