Repeat Problem, but the cycle can now contain superheated steam. The steam temperature in the cycle can be no higher than 600°C. In addition, the steam quality in the turbine cannot fall below 0.85.
Problem
A basic Rankine cycle is to produce 200 MW of power. The inlet steam pressure can be no higher than 15 MPa, and the outside environment is 15°C. The isentropic efficiency of the turbine is 0.80, and the isentropic efficiency of the pump is 0.75. Design a basic cycle, specifying state properties at each state, the required mass flow rate of the steam, the thermal efficiency of the cycle, and the required mass flow rate of either cooling water or air in the condenser.
