A 0.6 m3 rigid tank initially contains refrigerant-134a in saturated vapor form at 0.9 MPa . As a result of heat transfer from the refrigerant, the pressure drops to 240 kPa. Use TESTCalc to answer the following questions. a) Determine the final temperature (T2). b) Determine the amount of refrigerant that condenses. c) Determine the heat transfer (Q).
(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?
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 with a total volume of 0.8m3 initially contains
water in the form of a saturated liquid-vapour mixture at
P1=500kPa. The liquid portion of the mixture initially occupies a
volume of only 0.5L (the remainder is vapour). Steam from a supply
line at Pi=1000kPa and Ti=500°C is then injected into the tank
until the pressure in the tank reaches P2=800kPa. At this point
(final state), the mass in the tank is m2=2.8kg.

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).
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 rigid tank with a volume of 0.117 m3 contains 1 kg of R134a vapor at 240 kPa. Determine the initial pressure and final temperature.
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. 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.
