Determine the final volume of the water in cubic meters and in liters. What is the volume occupied by the water vapor? What is the volume occupied by the liquid water?

A frictionless piston-cylinder is filled with 3 liters of water at 250 kPa. Initially the temperature of the water is 20 °C. The water is heated until its temperature is 127.41 °C, and the quality of the steam is 0.6. Determine the final volume of the water in cubic meters and in liters. What is the volume occupied by the water vapor? What is the volume occupied by the liquid water? Show this process on a sketch of a T-v diagram, with the saturation dome shown for reference.
