Two containers are filled with air, one a rigid tank A, and the other a piston/cylinder B that is connected to A by a line and valve. The initial conditions are: mA = 2 kg, TA = 600 K, PA = 500 kPa and VB = 0.5 m3, TB = 27°C, PB = 200 kPa. The piston in B is loaded with the outside atmosphere and the piston mass in the standard gravitational field. The valve is now opened, and the air comes to a uniform condition in both volumes. Assuming no heat transfer, find the initial mass in B, the volume of tank A, the final pressure and temperature and the work, 1W2.
