A piston-cylinder arrangement contains water at 112°C, 84% quality with a volume of 0.98 L. What is the initial mass, in grams? The system is then heated, causing the 150-mm-diameter piston to rise and encounter a linear spring with k = 800 kN/m. Calculate the specific internal energy (kJ/kg) at this instant knowing that the measured volume is 1.65 L. The heating continues and compresses the spring in the process. When the piston encounters the stops, the pressure is 200 kPa. What is the temperature (in °C) and entropy (in J/K) at this point? Heating then continues until the pressure reaches 300 kPa. What is the volume, in L, at this instant? Illustrate the complete process in separate P-v and T-v diagrams.
