A 160 m3 rigid tank is filled with saturated liquid-vapor mixture of water at 50oC. 70% of the mass is vapor and the 30% of the mass is liquid. The mixture is then heated until its pressure is 50kPa. Determine the final temperature(oC).
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 0.3 m3 rigid tank is filled with saturated liquid water at 200°C. A valve at the bottom of the tank is opened, and liquid is withdrawn from the tank. Heat is transferred to the water such that the temperature in the tank remains constant. Determine the amount of heat that must be transferred by the time 2 of the total mass has been withdrawn. a. Hint: The phase of the water when / of the mass has exited is...
Don’t round any decimals please A 160 m3 rigid tank is filled with saturated liquid-vapor mixture of water at 50 C.0.89 of the of the mixture in unit of m2/kg. Round the result to 4 decimal places.
A rigid tank is filled with 260 kg of saturated liquid water at 200°C. A valve at th bottom is opened, and liquid is withdrawn from the tank. Heat is transferred to th tank such that the temperature remains constant. Determine the amount of hea the water remains a saturated liquid the entire time and that the veloc elevation change of the water leaving is negligible. (15 pts) st be transferred by the time half the mass has been withdrawn....
QUESTION 2 A 1.2-m tank is filled with water mixture at 200°C. If 90% of the mass is liquid and the rest is vapor, what is the total mass in the tank? (in kg) 130.8 75.2 87.2 116.3 101.7
(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 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 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.
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)
