Unformatted text preview: boiler pressure is kept at 8 MPa, the reheat section at 600 kPa and the condenser at 15 kPa. The
moisture content of the steam at the exit for both turbines is 10 %.
Find the temperature at the inlet of each turbine and the cycle’s thermal efficiency. Solution:
Assumptions: 1. Steady operating conditions exist. 2. Kinetic and potential energy changes are negligible.
