1. An adiabatic turbine has steam entering at 5 MPa and 800 C. The steam leaves as saturated vapor at 100 kPa. The flow of steam is 5 kg/s. The outlet velocity is negligible and PE/K.E. effects are negligible. a. What is the incoming specific enthalpy in standard units? b. What is the exiting specific enthalpy in standard units? c. What is the total power from the turbine in kilowatts? 2. Liquid water is at 101kpa and 40C. It is cooled to 20C. Using tables, find the specific entropy change (s2-s₁) in kJ/kgK. Used saturated liquid conditions at both temperatures. 3. For problem #2, calculate the specific entropy change using the heat capacity for liquid water. 4. A heat engine (H.E.) cycle receives energy from a 1000C source. It rejects energy to environment at 25C. What is the maximum possible thermal efficiency (n) of the H.E.?
