1. Correct Answer:8.0087 ± 0.1%
Steam at 1 MPa, 593.2oC,expands in a turbine to 0.01 MPa. If the process is isentropic, find the specific entropy (kJ/kg-K) at the exit ofthe turbine.
Note: Give your answer to four decimal places.
2.  CorrectAnswer:301.43± 0.08%
Initially, an insulated rigid tank contains 19.37 kg of water at27.04oCand 101 kPa. The tank also contains a 4.42 kg copper block at87.13oC.Assume constant specific heats where Cwater= 4.179 kJ/kg-K and CCu= 0.385 kJ/kg-K. Determine the final equilibrium temperature(K).
Note: Give your answer to two decimal places.
