A closed, externally well-insulated rigid tank having a total volume of 0.6 m is divided into two sections by a partition. Initially one section contains 0.4 m of hydrogen (H) gas at an absolute pressure of 2 bar and an absolute temperature of 400 K while the other section contains 0.2 m of nitrogen (N2) gas at an absolute pressure of 4 bar and an absolute temperature of 300 K (State 1). The partition is free to move and allows heat transfer between the two gases until mechanical and thermal equilibrium is achieved (State 2). Assume constant specific heats for both gases. For hydrogen: Molecular weight = 2.016 kg/kmol; Specific heat at constant pressure cp = 14.427 kJ/kg-K For nitrogen: Molecular weight = 28.013 kg/kmol; Specific heat at constant pressure cp = 1.038 kJ/kg-K Determine the entropy generation during the process, in kJ/K.
