A cylinder with a constant load on the piston contains water at 500 kPa, 20 C and volume of 1 L. The bottom of the cylinder is connected with a line and valve to a steam supply line carrying steam at 1 MPa, 200 C. The valve is now opened for a short time to let steam in to a final volume of 10 L. The final uniform state is two phase and there is no heat transfer in the process. What is the final mass inside the cylinder?
