4.40 A rigid, insulated tank consists of two compartments of equal volume separated by a valve. Initially, one compartment contains air at a pressure of 750 kPa and a temperature of 50°C, while the second compartment is completely empty. The valve is opened and it remains open until the two compartments reach pressure and temperature equilibrium. Determine the final pressure and temperature of the air, assuming each compartment has a volume of 0.65 m'.

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...

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...

Consider 0.7 kg of N2 at 300 K, 1 bar contained in a
rigid tank connected by a valve to another rigid tank holding 0.3
kg of CO2 at 300 K, 1 bar. The valve is opened and gases
are allowed to mix, achieving an equilibrium state at 280 K.
Determine:
(a) the volume of each tank, in m3.
