An adiabatic cylinder of volume 10 m3 is divided into two compartments A and B, each of volume 6 m3 and 4 m3 respectively, by a thin sliding partition. Initially the compartment A is filled with air at 6 bar and 600 K, whilst there is a vacuum in the compartment B. Suddenly the partition is removed, the fluid in compartment A expands and fills both the compartments. Calculate the Loss in available energy. Assume atmosphere is at 1 bar and 300 K.
