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 initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...

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...

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...

4. A 1.5-m rigid tank is initially empty. Refrigerant (R-134a) in the supply line at 750kPa and 20°C is connected to the well-insulated tank through a valve. The valve is opened, and R-134a enters the tank until the pressure in the tank reaches the pressure of 500 kPa, at which point the valve is closed. (a) Write the assumptions. (b) Show the 1" law of thermodynamics with a control volume. (c) Determine the final temperature in the tank. (d) Determine...

1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...

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...

(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?

4) Volume 2.5 m^3 air in a rigid tank with initial pressure 100 kPa and temperature 25°C There. It is applied to the tank feed line by a valve. Pressure of air flowing through the supply line 600 kPa and temperature is 25°C. By opening the valve, the pressure of the air in the tank is air entering the tank until it is equal to the pressure of the air It is closed. A thermometer placed in the tank lasts...
