A 0.145 m rigid tank initially contains refrigerant-134a at 1 MPa and 100 percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a ad.2 MPa and 36°C. Now the valre is opened, and the refrigerant is allowed to enter the tank. The valve is closed when it is observed that the tank contains saturated liquid atl.2 MPa. Determine (a) the mass of the refrigerant that has entered the tank 156.057g(Kound to three decimal places)...

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...

0.4 kg of Refrigerant 134a initially fills a piston–cylinder device with a volume of 15 L at a pressure of 400 kPa. The cylinder is connected to a supply line through a valve. R-134a is flowing in the supply line at 900 kPa and 45°C. The valve is opened, and R-134a is allowed to enter the cylinder. The valve is closed when the volume of the cylinder is triple and the temperature in the cylinder reaches 15°C. During the process,...

1- A fixed mass rigid tank is filled with Refrigerant-134a. Assuming initially, R-134a is under 160 psia and saturated condition (quality, x, = 1.0). The volume of tank is 20 ft. Then it went through a process until the final pressure, P, reduced to 50 psia, and the heat transfer occurred during this process. Determine (a) the final temperature, (b) the amount of R-134a been condensed, (c) the net heat transfer. (15 points)

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...
