  • 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)

    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.

  • 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 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.

  • (1 point) A rigid, insulated 0.43 m tank initially contains saturated water liquid at 362 kPa....

    (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?

    An insulated 1.7 m3 rigid tank contains air at 500 kPa and 50oC. A valve connected to the tank is now opened and air is allowed to escape until the pressure inside drops to 200 kPa. The air temperature during this process is maintained constant by an electric resistance heater placed in the tank. a. Determine the mass of air initially, m1 in kg. b. How much air escaped from the tank, mout in kg. c. Determine the electrical work...

    1 A piston-cylinder device initially contain 0.4 m3 of 1.8- kg saturated liquid water and steam mixture at 110 kPa. A electric heater in the device is turned on and passes a current of 1.7 A from a 120-V source. Only transfer of electrical work and boundary work exist. The piston initially rests on a set of stops, and a pressure of 200 kPa is required to move the piston. Afterwards the system continues to raise the piston and eventually...
