A piston-cylinder device initially contains 1.78 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. Determine (a) the final volume of the tank, m (Round to six decimal places.) (b) the final temperature and pressure, MPa and (c) the internal energy change of the water kJ 0 Water 1.78 kg 200 C
A well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 100 kPa
A well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 100 kPa. Initially, three-quarters of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized. Determine the entropy change of the steam during this process. Answer: 8.10 kJ/K Analysis From the steam tables (Tables A-4 through A-6)

2) A) Water, initially saturated vapor at 10.8 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored. B) A piston-cylinder assembly contains 2 kg of water at 210.6oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.7 bar. During compression, there is a heat transfer of energy from the...
A well-insulated rigid tank contains 5.80 kg of a saturated liquid-vapor mixture of water at 225 kPa.
A well-insulated rigid tank contains 5.80 kg of a saturated liquid-vapor mixture of water at 225 kPa. Initially, one-quarter of the mass in the liquid phase. An electric resistor placed in the tank is connected to 240-V source, and a current of 6 A flows through the resistor when the switch is turned on. Determine how long it will take to vaporize all the liquid in the tank in minute.
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa, 40% of the mass is in the liquid phase. A heater is providing heat to the content of the tank so that all liquid phase converts to vapor phase. Calculate the entropy change of water in this process.

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...

Water contained in a closed, rigid tank, initially saturated vapor at 200°C, is cooled to 101.3°C. Determine the final pressure, in bar.
rigid tank
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...
