A vessel of capacity 0.3 m3 is insulated and divided into two sections by a partition. One section is 0.2 m3 in volume and initially contains H2 at 2 bar and 127°C. The remaining section initially holds N2 at 4 bar and 27°C. The adiabatic partition is then removed, and the gases are allowed to mix. Determine : (i) The temperature of the equilibrium mixture, (ii) The pressure of the mixture, and (iii) The change in entropy for each component and total value. cv(N ) 2 = 0.744 kJ/kg K, cv(H ) 2 = 10.352 kJ/kg K cp(N ) 2 = 1.041 kJ/kg K, cp(N ) 2 = 14.476 kJ/kg K.

Question
A vessel of capacity 0.3 m3 is insulated and divided into two sections by a partition. One section is 0.2 m3
in volume and initially contains H2
at 2 bar and 127°C. The remaining section initially holds N2
at 4 bar and
27°C. The adiabatic partition is then removed, and the gases are allowed to mix. Determine : (i) The temperature of the equilibrium mixture,
(ii) The pressure of the mixture, and
(iii) The change in entropy for each component and total value.
cv(N ) 2 = 0.744 kJ/kg K, cv(H ) 2 = 10.352 kJ/kg K
cp(N ) 2 = 1.041 kJ/kg K, cp(N ) 2 = 14.476 kJ/kg K.
