Consider a Rankine power plant that has uses no reheat with water as the working fluid. The steam generator operates at 100 bar and the condenser operates at 10 bar (absolute). The water enters the turbine at a temperature of 775 degrees Celsius. Assume no losses in the system. What is the specific enthalpy and the specific entropy of the water as it enters the turbine
