A steam turbine operating with less moisture is ____________ (more/less) efficient and ________ (less/more) prone to blade damage.

In a steam power plant operating with simple Rankine cycle, the turbine is fed with steam at $$100$$ bar and $$673$$ $$K.$$ Determine the actual enthalpy and quality of the steam extracted at $$14$$ bar if the turbine stage efficiency is $$90$$ percent.

Subsonic and supersonic diffusers have the following geometry:

In stream and other vapor cycles, the process of removing non-condensables is called
