A 1 m 3 isolated chamber with rigid walls is divided into two compartments of equal volume.
Question:
A 1 m3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum. The partition is ruptured, and after sufficient time for the system to reach equilibrium, the temperature and pressure are uniform throughout the system. The objective of the problem statements below is to find the final T and P.
The gas follows the equation of state
where b = 20 cm3/ mole; a = 40,000 cm3K/mole; and CP = 41.84 0.084T(K) J/mol-K.
(a) Set up and simplify the energy balance and entropy balance for this problem.
(b) Derive formulas for the departure functions required to solve the problem.
(c) Determine the final P and T.
