2.) An actual Rankine Engine is used to power a generator. The steam
enters its turbine at 4 MPa and 300C then expands in an irreversible
adiabatic process where it becomes saturated vapor. It enters the
condenser with a pressure of 5 kPa. Find Ec, W(W₁, W₁, Wk) the
remaining engine efficiencies(n,, na, nx), thermal efficiencies (e₁, 3,
ek), SR(SR₁, SR₂, SR), HR(HR, HR, HR) obtained if the
turbogenerator has 85% mechanical efficiency and 90% generator
efficiency. 2822.88
