Steam enters a turbine with a mass flow rate of 25 kg/s. The inlet pressure is 100 bar, and the inlet temperature is 400 C. The outlet contains saturated steam at l bar. a) Apply and formulate the first law of thermodynamics for this process. Potential and kinetic energies can be neglected. (10 Points) b) At steady-state, calculate the power generated (kW) by the turbine. [5 (correct assumptions) + 5 (correct formula) + 12 (correct calculation) + 3 (correct data reference) + 5 (correct answer and units) = 30 Points] c) Does the work done is positive, negative or remains the same? Explain. [10 Points] Note: Explain your answer where required
