PROBLEM 2 (35 points). An insulated, rigid tank whose volume is 0.5 m3 is connected by a valve to a large vessel holding steam at 60 bar, and 440°C. The tank is initially evacuated. The valve is open only as long as required to fill the tank with stream to a pressure of 40 bar. As this occurs, a paddle wheel adds 260 kJ per kg of work to the tank (where the kg mass for this work represents the...

SP04 A rigid, poorly insulated tank with a volume of V1.0 m3 initially contains a saturated water vapor (quality of 1.0) at a pressure of 3 bars (300 kPa). The tank is connected to a supply line containing steam at a pressure of pL- 10 bars (1000 kPa) and a temperature of TL 500°C. The valve is opened and 2.0 kg of steam enters the rigid tank, after which the valve is closed. The pressure is measured after the valve...

A 2.2-m3 rigid tank initially contains air at 100 kPa and 22°C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22°C. The valve is opened, and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is...

An insulated, rigid tank that is initially evacuated is connected by a valve to a nitrogen supply line. The nitrogen in the line flows at 30°C and 80 kPa. The valve is then opened and nitrogen flows into the tank until the pressure reaches 80 kPa; at which point the valve is closed. Using constant specific heats at room temperature (Cp = 1.039 kJ/kgK, Cv = 0.743 kJ/kgK, k. = 1.3984), determine the final temperature of the nitrogen in the...
