A steady-state, well insulated turbine operated in two stages in series using steam . The first stage has an efficiency of 85% and the second stage 90%. Steam enters the first stage at 400 C degree and 4 MPa and exits at 1.5 MPa. The steam then enters the second stage and exits at 100 kPa . Show the process in a T-S diagram. Also determine the work developed by each stage.
