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 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)
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.

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...

A 200-m' rigid tank is filled with saturated liquid-vapor mixture of water at 50°C. If 10% of the mass is liquid and the rest is vapor, find the total mass in the tank. If heat is added in and the mixture becomes saturated vapor, find the pressure.

(1 point) A rigid, insulated 0.43 m tank initially contains saturated water liquid at 362 kPa. The tank is connected to a steam pipe line carrying steam at 1.53 MPa and 305 °C through a valve. When the valve is opened, steam enters the tank from the pipe. When the valve is closed, the tank is filled with a saturated vapor with a pressure of 0.8 MPa. How much mass was added to the tank during this process?

A rigid, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquid-vapor mixture at 200 kPa, consisting of 0.04 kg of saturated liquid and 0.04 kg of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at a pressure greater than 138 kPa. Kinetic and potential energy effects are negligible. For the water, determine...
