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 (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar.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 1: (400 points) A piston-cylinder assembly contains a two-phase liquid mixture of Refrigerant 22 (R22) initially at 24°C with a quality of 90%. Expansion occurs to a state where the pressure is 1 bar. During the process, the pressure and specific volume are related by pvos = constant. Determine 1. The work per unit mass [kJ/kg). (200 points) 2. The heat transfer per unit mass (kJ/kg] during the process. (100 points). 3. Show the process on p-v and T-v...

An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
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 sealed rigid tank contains 5.0 kg of water (liquid plus vapor) at 100 oC with a quality of 30.375%. Using the Thermodynamic Tables that accompany the textbook and the relationship between quality and other thermodynamic properties: Calculate the specific volume of the water. Determine the mass of water in the vapor phase. Determine the saturation pressure and temperature of this water if it had the specific volume calculated in part (a) and a quality of 100%. Determine the amount...
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.

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?
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...
