P5-16. A tank contains a two-phase mixture of steam and water at 40 psia. If the volume of the vapor is 10 times the liquid, what is the quality?
Problem 5(25 points) A rigid tank initially contains a partition that separates water at two different states. One side of the partition initially contains 4.5 lbm of steam at 150 psia and 600°F. The other side of the partition contains 7 lbm of saturated liquid 25 percent. The pressure at the final state is 50 psia. -vapor mixture at 300°F with a vapor mass fraction of partition is removed, and mixing occurs until equilibrium is established. The a) b) Determine...
Problem 5- A piston-cylinder device initially contains steam at 3.5 MPa, superheated by .10°C. Now, steam loses heat to the surroundings and the piston moves down, hitting a set of stops, at which point the cylinder contains saturated liquid water.
