Two containers, A and B, are separated by a division. Initially, Tank A contains 5lb of water at 170Psia and 600 ° F, while Vessel B contains 7lb of water, at 300 ° F, with 60% mass fraction of vapor. The division is then removed, and the two sides are allowed to mix, until mechanical and thermal equilibrium is established. If the end-state pressure is 60 Psia, determine the entropy change in the system. Note : dear expect please mention which property table you used
An insulated tank of volume 4 m³ is divided into two equal compartments by a thin and rigid partition. One compartment contains an ideal gas at 708 K and 363 kPa, while the other is completely evacuated. Now, the partition is suddenly removed, and the gases are allowed to mix. The equilibrium is reestablished by equalizing the pressure and the temperature. Estimate the change in entropy of the gas kJ/K.

Steam enters a turbine at 100 bars and 400°C. At the exit the pressure is 1.0 bar and the entropy has increased by 0.600 kJ/kg K under adiabatic conditions. The changes in kinetic and potential energies may be neglected. (a) Determine the work, in kJ/kg. For the same initial conditions and final pressure the turbine is now run without insulation. The entropy production due to internal irreversibilities is assumed to be the same as in part (a). However, the environment at 300 K is found to have an entropy change of +0.0800 kJ/(kg steam) · K. Also, the entropy change of the steam due to heat exchange with the environment has an absolute value of 0.0460 kJ/kg · K.
