Asimple non-ideal rankine cycle with water as the working fluid operates between the pressure limits of 15 mpa in the boiler and 125 kpa in the condenser. saturated steam enters the turbine. irreversibilities in the turbine cause the steam quality at the outlet of the turbine to be 70 percent. determine the isentropic efficiency of the turbine and the thermal efficiency of the cycle.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
