A frictionless piston-cylinder device encloses 0.226 kg of saturated water-vapour mixture which is initially 10% by mass in liquid. The initial pressure is 1.035 MPa. The fluid is now heated until it all becomes saturated vapour. a. Find the work done during the process. Now, suppose that there is a stop in the cylinder that limits the piston to stop at the top when the volume is 0.0424 m'. b. Find the quality of the mixture when the piston just reached the stop, i.e. when the fluid volume is at 9.0424 m'.
