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.
Water contained in a closed, rigid tank, initially saturated vapor at 200°C, is cooled to 101.3°C. Determine the final pressure, in bar.
Air is contained in a 100 liter rigid tank and is initially at 40 oC and 900 kPa. The air is cooled until the pressure drops to 400 kPa. Find the final temperature and the amount of heat transfer during the process. Consider air as ideal gas with constant specific heat.
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 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).

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.
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...
