A rigid tank having a volume of 0.1 m3 initially contains water as a two-phase liquid-vapor mixture at 1 bar and a quality of 1%. The water is heated in two stages: Stage 1: Constant-volume heating until the pressure is 20 bar. (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar. (Note: Use transient analysis with all the water leaving having a quality of...

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...

An insulated rigid tank initially contains 5 lb of saturated liquid water-vapor mixture at 40 psia with three-quarters of the mass in the liquid phase. An electric resistance heater placed in the tank is turned on until all of the liquid is vaporized. Calculate (a) the exergy destroyed, and (b) the second law efficiency.

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 125 kPa. Initially. 3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 10%. We denote the...

The rigid tank illustrated in fig P4-124 has a volume of 0.06m^3 and initially contains a two-phase liquid -vapor mixture of H2O at a pressure of 15 bar and a qualityof 20%. As the tank contents are heated, a pressure-regulating valve keeps the pressure constant in the tank by allowing saturated vapor to escape. Neglecting kineticand potential energy effects:(a) Determine the total mass in the tank, in kg, and the amount of the heat transfer, in KJ, if the heating...
