1. Correct Answer: 8.0087 ± 0.1% Steam at 1 MPa, 593.2^oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the specific entropy (kJ/kg-K) at the exit of the turbine. Note: Give your answer to four decimal places.
2. Correct Answer: 301.43 ± 0.08%

Initially, an insulated rigid tank contains 19.37 kg of water at 27.04^oC and 101 kPa. The tank also contains a 4.42 kg copper block at 87.13^oC. Assume constant specific heats where C_water = 4.179 kJ/kg-K and C_Cu = 0.385 kJ/kg-K. Determine the final equilibrium temperature (K).

Note: Give your answer to two decimal places.
